There are a few pathological liars here- and there are a few that are conspiracy theory nuts, and a few that are somewhat reasonable.
Thank God I don't have to deal with liars and the conspiracy theory nuts in real life.
I use to. My wife's best friend's husband peddles some in conspiracy theories, mainly political ones. We use to be good friends but he went down this road pretty far after Trump had been in office a few years. He was never a big Trumper though.
About a year ago he was at my house in the summer for one of our summer BBQs where we take friends and family out on the lake and then we have a big BBQ here at our property. For some reason, he started up a conversation with my father in law about some conspiracy theory stuff of his that was political. My father in law doesn't like political stuff at all and doesn't want to talk about it and I could overhear the conversation. Eventually, I stepped in and told him if he couldn't change the conversation, I'd ask him to leave and not come back to my house and a few other things where he got the message his opinions on such topics weren't welcome.
My wife got a bit upset with me, but I told her I wasn't going to entertain that crap at my house, especially from a guest. He got the message, changed the subject and has never mentioned it again. I appreciate that and respect him for that. He knows I have not a problem in the world telling him to not come back to my home. I can be damn direct in person if necessary and everyone that knows me knows it.
My wife later told me his wife gets upset when he starts talking his crazy talk but she just has to put up with it. She's a great lady and I respect her for that too.
Thankfully, he got the message, and we've had some nice visits since then and things are fine and we've moved on. We aren't friends like we use to be- I wouldn't consider us friends at all now- but we can talk and hang out a few times a year without a problem.
