With goals like that, I'm really not sure what you hope to accomplish. Even by not engaging with the topic, you still engage with him. Your stance doesn't matter. On the black and white forum of lemmy, simply by replying, you're disagreeing. Lines have been drawn and nothing said will do any good or change anyones mind on anything. You are still engaging in the culture war.
Let the mods clean it up if he goes too far.
I still think you're both weird
Nothing about either of your positions are "normal" the ultra rich are fueling a culture war, and the internet trogoldyte laps that shit up.
The rise of trans ideology making its way into the mainstream directly links with the occupy wallstreet movement and gay marriage legalization.
The ultra-rich have created a boogeyman, to distract and divide us, and now you all sit around defending or attacking it.
The average person does not spend their day mass posting on Lemmy and then arguing about gender in the comments.
Pointless.
You're both useful idiots in this culture war though. You've both turned non-issues into hills to die on. And like the other guy said, little by little radicalized "normal" people into picking a side and making it a key part of your personality.
Weirdos.
