That is assuming everyone else is too stupid to make that decision for themselves.

Who gets to decide what is acceptable and what isn't?

Our/society's rights and wrongs has greatly changed over time and that is only possible because of both good and bad ideas being heard.

No one person should be deciding what's acceptable for the whole of soceity. Every individual should hear different ideas, good, bad and terrible, and decide for themselves what/who they agree with.
