I think you get bombarded with hate because of the larger problem of extreme polarization on social media. All subtlety is lost, you are associated with the one anti-science group, opposed to the one pro-science group.
It's kind of mixture of online and real-life experiences. In real-life you dont get the hate, but only because they know, it would be extremely rude. But they have other things, eg. make jokes about you to others.
