It is refreshing to still use a technology which mainly has not been tainted with current crap (share, like, subscribe). You have to deal with some mods on power-trips, but it is rare. Happy thirty!
Not too rare. Several channels are held to their project's Code of Conduct. And some of those CoCs require you to agree to use x-based pronouns when someone requests it, or else banned until you change your mind.
The only time I think it’s fair to draw a line is if someone tries to dictate how you refer to other people, which is frankly none of their business. These CoC are really just “don’t be a dick, respect each other,” written down. If that’s burdensome to someone, that person has issues. If calling what you believe to be a “he” a “she” is really that hard, then that is definitively your problem.
