The problem is that the activist crowd not only doesn't understand this basic fact and also overwhelmingly they don't understand basic writing/storytelling and how it works, they think that characters going through bad things is proof that the writers hate the characters and want to use them as a proxy to punish whatever the character represents, because that's exactly what they would do to characters, only instead of the characters being minorities or women, they'd focus Bad Things™ happening to Straight White Cis Males. In other words, they're projecting again.
It's like they're the mirror image of the Moral Majority's objections to violence and sex in media, which was brilliantly parodied in the Simpsons episode where Marge goes on a campaign to make Itchy and Scratchy non-violent.
