I have a family member who seems to buy into a lot of conspiracy theories/ extreme views. For example is an antivaxxer, follows Andrew Tate, believes we should all be allowed to own guns, all drugs should be legalised, doesn't believe that racism should be challenged (basically thinks it's fine if people are racist).
He is just so extreme about everything that you can't even have a conversation with him.
He recently went to hospital and gave a fake name because he was is so utterly paranoid about anyone having any information about him. He has a huge mistrust of the UK government.
He had some treatment and did give them his real address and he got a letter asking for payment (because the fake name he gave was not a UK resident). He was just laughing about it.
How do I even continue a relationship with someone like this? He is so extreme, I don't know what to do. AIBU to just distance from him even though I care about him? Is there any way to talk to someone who seems to be basically brainwashed?
