Just for your information, as a non-binary person who was assigned female at birth (so definitely under-represented in EA), I would find it very upsetting if I knew you were trying to control which ideas and people I was exposed to.
I find speciesist attitudes morally offputting, but if you would keep events from me because some people there were speciesist, I'd consider you to be being a bad friend.
People are different. Some people consider what you're suggesting to be helpful. I do not. I just want you to be aware about the differences in preferences there, and not think that all "underrepresented groups" would feel uncomfortable going to events with speakers they deeply disagree with.
I've actually read probably over 100 of his articles, and that's what's convinced me he's not racist.
How much of his original content have you actually read? You can just check if you want. His writing is out there.
I think most of people thinking he's racist have looked at one or two cherry-picked tweets and read articles written by other people about him and what he said, instead of looking at what he actually said.
It's important to note that few people will share their negative experiences with the Community Health Team because the CHT blacklists people from funding, EAG attendance, job opportunities, etc.
Also, if they cause people to leave the community, you're unlikely to hear about it because they've left the community.
This leads to a large information asymmetry.
I know many people who's lives and impact have been deeply damaged by the CHT but they won't share their experiences because they are afraid of retaliation or have given up on the EA community because of them.
