If X doesn't offend you, why would self-modify to make X offend you to stop people from doing X, since X doesn't offend you?

Surely there are a great many reasons other than offense why, for various different things X, it might be (or seem) useful to me to stop you from doing thing X. For example, if thing X is "mocking my beliefs": if my beliefs are widely respected, I and people like me will have a larger share of influence than if my beliefs are widely mocked.
