If you are told all day that you are under attack, then go onto a supposedly more tolerant space and what you see if people attacking you, then it's naïve to think it will not affect you.
This is just a massive own goal, and is entirely avoidable by targeting the right butt of the joke, rather than aiming large, having collateral damage and saying "you're only offended if you feel targeted". That's not fighting the good fight, that's just being a hateful shithead on the internet.
