Ok I shall reply a bit on the Full of Error video now that I
have some time.
I have decided to refute every ridiculous claims in this
video
(unfortunately there are
countless of such 'evangelical', 'propaganda' videos that is a
complete distortion or misunderstanding of Buddhism. so any more of
such crap videos coming up, I'm just going to refer them to this
topic.)
At 2:47, Their days will
be spent in hunger and poverty. They will not work and they will
beg for food. They will have no family lives and they will have
nothing to wear but these clothes. And what is more, they will do
all these in the superstitious belief in order not to be reborn as
a fly or a mouse.
This is absurd to the point of...

Firstly monks are not hungry because there are lots of followers
who give them alms, on the material level they are adequate and
stable, and secondly they have realised the true gems and wealth of
the universe is only to be found in the Three Treasures (Buddha,
Dharma, Sangha).
The ultimate aim of Buddhism is liberation, nirvana, not just being
reborn in higher realms and creating better karma. Anyone - even
non-monks - can create good karma and be reborn in heaven. In fact
even lay people can practise and be enlightened, liberated.
The reason why some Buddhists chose to renounce? Because they wish
to wholly concentrate their lives on the practising of the dharma
leading to the great liberation and serving the lays.
Ok. Next, at 3:16, For
Buddhists, who spend their days in pointless irrational rituals,
life is always dark and stagnant.
Again, that is not understanding Buddhism's Sangha and monastic
community at all. Rituals take up very little time of a Monk's
life. A monk seeks to learn the dharma, practise the dharma, and
serve the lay people. Useless rituals are shunned and rejected by
Buddhism. Meditation is certainly not a ritual, but a practise to
develope concentration and insight, and so is chanting. Another
purpose of chanting is to gain knowledge of the scriptures and make
sure that one is well versed, knows the words of the Buddha
well.
In fact, one of the fundamental defilements that drops away at
first awakening (the stage of Sotapanna or Stream-enterer) is
attachment to rites and rituals, i.e. Buddhism, ceremony, specific
techniques, and religious and cultural trappings in general.
Next. At 3:28, Furthermore, among all these rituals,
Buddhism cause people to forget God or even to deny
him.
What a bunch of crap.. let's not talk about the rituals, but in the
first place, does Buddhism even teach about a Creator? 
Quite unlike Buddhists, those who live under the moral
values of Islam are always productive, happy, and at
peace.
Some kind of propaganda nonsense. I am not questioning Islam's
goodness, but to say that Buddhists are not productive, happy and
at peace is absurd. I'm sure the author has not met any true
Buddhists and is merely trying his best to badmouth Buddhism to the
best of his ability (and a very bad attempt)
Buddha chose to speak about his basic tenets and hand on
his form of worship orally.
Buddhists don't worship any supreme deities.
The only subject matter in this book is people suppressing
all their desires and trying to train souls living in poverty and
suffering.
Buddhism teaches liberation from desires, not
suppressing. Suppressing seems like putting a rock on top of a weed
but once the rock is removed, it grows again. But liberation means
the root of the weed (of Ignorance) is uprooted.
Secondly: Buddhists practise middle way of neither the extreme of
luxurious wealth, and the other extreme of ascetism.
Buddhists build their lives on supppressing human wishes
and desires and by performing various rituals.
Suppressing human values and desires --> explained above.
Rather, Buddhists aim to develope insights and looking into the
very nature of existence, and as a result we free ourselves from
false notions such as a permanent and seperate self, or seeing
permanence whereas the truth is they are impermanent.
Actually when Buddha said 'Desire is Suffering', we must be careful
in understanding it. Dharma Dan said: Craving, attachment, and desire are
some of the most dangerous words that can be used to describe
something that is actually much more fundamental than these seem to
indicate. The Buddha did talk about these conventional forms of
suffering, but he also talked about the fundamental suffering that
comes from some deep longing for a refuge that involves a separate
or permanent self. We imagine that such a self will be a refuge,
and so we desire such a self, we try to make certain sensations
into such a self, we cling to the fundamental notion that such a
self can exist as a stable entity and that this will somehow help.
The side effects of this manifest in all sorts of additions to mind
states and emotions that are not helpful, but these are side
effects and not the root that cause of suffering that the Buddha
was pointing to.
Rituals --> pure lol.
The process of turning Buddha into an ideal began
immediately after his death. Buddhist priests set to make him
Divine. They adorn the places they live and with great statues of
the Buddha and superstitiously worship these idols they made with
their own hands.
Firstly, Buddha is an ideal because he taught that everyone could
attain enlightenment like him. The theory that 'Buddhist priests'
(btw is monks or nuns, not priests) make him divine or make him
into an ideal is plain queer and without basis.
Secondly, Buddha himself allowed (in his lifetime) his disciples to
make images of him while he travels to preach his mother in the
heavens. That is the beginning of the tradition of making images
and statues of Buddha. However, we do not worship any forms
and images of Buddha. Instead, we pay reverence and
respects to the Buddha, treating him like our honoured
teacher, not a divine, supreme deity.
