Universalism cannot be classified as "false views". All
religions have some truths in them, along with some distortions.
When you have the belief that your "religion" is the only way, then
you no different from a fundamentalist -> the belief in old and traditional forms of
religion, or the belief that what is written in a holy book is
completely true.
As for whether need to voice out against false views,
it is depends more on the individual who is going to receive the
comments.
Personally, I do not mind people telling me that I have "false
views" as I do not have a fixed belief anyway.
However, if you are to tell a closed-minded person that he/she has
"false views", he/she may reject 100% of what you said and may even
get angry.

In the case of words that the Tathagata knows to be unfactual,
untrue, unbeneficial (or: not connected with the goal), unendearing
and disagreeable to others, he does not say them.

true, beneficial, but unendearing and disagreeable to others, he
has a sense of the proper time for saying them.

Tathagata has sympathy for living beings.
