Some can sound utterly snobbish but come out sounding stupid
instead.

Agreed, this facebook threadstarter is not a snob la, the writer
is just some loser trying very hard to be snobbish. If the writer's
English is so impeccable, then you wouldnt see elementary
grammatical errors glaring right into your eyes in the last
sentence. If the writer wants to rant about good English, the
writer should take in account of proper punctuation too! Which, oh,
is so sorely lacking in the writer's tirade. 
So
the writer must be someone of "low standards"!
I can't believe there are such people out there who,
unreservedly, make such flippant comments without a dab of
embarrassment. Whichever the case, we oughn't bother because I am
pretty certain such obstinate sentiments yield no fruits in the
future, where Chinese takes precedence. So it will be a hard fall
for the writer! 
To add, it sounds more like a whimsy bitch who is trying too
hard to be an Ang Moh. :)
