Yes, it's possible that someone can be offended by requests not to offend others: a kind of second-ordered offense, if you will. However, such second-order offense is a result of an individual's self-defense against an offender, and under the framework I've discussed here and elsewhere is therefore justifiable.
Also, we're not talking censorship here, since no one's talking about government intervening to restrict the original offensive speech. We're not even talking about private censorship, because TFA doesn't even call on the community managers to ban the offensive speech. Rather, TFA is engaging in the classic anti-censorship response to harmful speech: more speech.
Finally, you didn't answer my question. Your prior posts take the position that there is nothing morally wrong with intentionally causing harm or discomfort to others (or perhaps even that you are morally entitled to do so) when there is an action those others could take that could protect them from you. Does your dodge indicate that you are backing away from that position?
