Just cos u don’t agree with someone for some of their ideas that’s no reason to cut them off. Tell him u don’t agree explain why and tell him u don’t want to discuss it with him and if he forces u to u will leave.

U can fundamentally disagree with someone and still have a respectful relationship.

Think about it from his perspective u are associating/supporting people he believe are just as bad as u believe elon/trump is. It sounds like he is still respectful of you for who you are.
