I've had a similar experience so now if I'm posting on those platforms I try to keep it light and wrap it in humour to get a message through. Many people can process a meme, but if you use too many words and need them to think a bit it is too much effort for them. If you look too partisan or land on a trigger then they will attack.

That's one of the reasons I like HIVE - people here are more open to ideas and will actually read stuff, and think for themselves!
