Encounter with a 19 year old man child theist

[Fireball]

Greetings. I've know theists all my life. I've had small talk with theists about my atheism and they mostly didn't care very much. I can see why; It's mostly pointless to argue about it when they better things to do. However, this time, rather recently, in fact, I had a real-life encounter with a crazy theist. He and I were in the same class through 8-10 grade when I was a teenager and this topic wasn't brought up until my junior year. 

I told him I was an atheist. He said in response "Why don't you believe in God?" I told him that I see no good reason to believe in such things. He then told me "You need to believe in God." I said, "Why?" He told the usual theist response, "He loves you", "He knows", etc. I pressed for how he knew that. It would always (like Clockwork) end in "Because I believe it." This started a firestorm. In the conversations afterward, he spilled his beliefs on me. He believes a lot of strange things. I won't list them here, for the sake of your time, but I a list on Pastebin. Be warned, however, you will be amazed or terrified:

This continued all year, until summer vacation, where I basically said "Fuck you." to him. I was so pissed at that point. He was so willfully ignorant and childish that it made me rage. This school year, I tried to establish good relations with him and teach him about science, but that failed utterly. He couldn't even agree on definitions, that's how willfully ignorant he was and is. His MO is still much the same, and I eventually gave up on him. He's basically a 9-year-old in 19-year-olds body. His behavior is constant with humans of that age. Playing real-life make-believe, think he's hot shit and living in fantasies to escape his meager life.  You would assume I was arguing with a kiddy. Nope. Full grown man. Young adult. A young 19-year-old Methodist Wesleyan. I wouldn't be here talking about this right now if he put about his beliefs and didn't force anybody to believe the same things he did. But he didn't. 

But it's not necessarily his fault; he lived in and grown in a bubble, an echo chamber where few if any of his peers questioned him about his beliefs or taught about escaping confirmation bias, learning about science, or critically thinking about the self. His father is a pastor, so he definitely was indoctrinated as a child. He never got the opportunity to learn like I did. His father thought that faith was a virtue, that being gullible was a gift to behold, rather than an auto-deceptive self-delusion that can make you believe your contact with Slenderman or think you bonked Sans from Undertale. In small words, it's no pathway to truth and a perfect system for protecting lies.

There's a thread here somewhere that discusses "firehosing", which is a method of lying so much with no regard as to whether it is true or if anyone even believes it. Of course the "hoser" may well have been indoctrinated in the same way. The original report was by the Rand Corporation, and discussed Russia. But the parallels with what is going on in the Trump administration are chilling. I think that firehosing is bad enough in and of itself, but if one starts their children off with it in the form of the parent's chosen religion, the kids don't stand a chance, in general. Many of us raised in xtian homes have managed to reason our way out of it. I don't call xtians stupid for it (except for a "Chosen" few, whom you meet, eventually), because I used to live in that sort of bubble, and I sure as hell ain't stupid. BTW, welcome!
