i tend to get pissed off about issues i care about and tend to go off on people, so i should honestly try and calm down before posting haha. however i do agree with gyro on the grounds that when people who are actually affected by these issues speak out (even if its agressively) tend to be the ones getting banned and shut down by people. i also think that people should really research before making threads, and making sure they know what they are posting about before posting. eg the thread about trans children transitioning. by the looks of it the OP meant medically, but it wasn't specific so it caused confusion eventually leading to threads being locked.
i also think that the mods should be better at handling these situations? like i appreciate the work they do to this forum such as stepping in when neccessary and banning people, but more warnings should be handed out for people who are notorious for hateful behaviour (eg, if somebody said "i think gay people should all die", the post should be removed and the user should get a warning, at the very least). also i think if a thread is locked (unless its a troll thread) a post should be made explaining why its locked from a mods pov.
tdlr if "being nice" means not standing up for yourself, then no. but if it means having respect for people, then yes.
