Let’s get something straight right here, rape culture is not simply doing something that someone else has expressed a distaste for. Going into a public forum that you do not own or have control over, asking/telling the people there to act a certain way, and them responding by ignoring that request is not rape culture.
If it was a more private situation, like a group chat among friends, or even a public forum but an individual discussion between a small group of 2-3 people talking directly to each other, respect should be given to requests. If you were having a back and forth conversation with someone, and asked them not to swear while talking with you, they should respect that. But coming into public forum and demanding everyone else adhere to your rules, then spouting “rape culture” if they don’t follow along, is only cheapening the phrase “rape culture” and removing meaning from it.
