1) The place has no basement
2) He did not have in appropriate pictures
3) The "Emails" where all about going to have pizza and some turd burger made a connection to something that wasn't there"
4) that's all on netflix too
2) He did have them on his social media profile and he was in support of a group that wanted more man/kid relationships. This wasn't part of the movie but I remember this going down on reddit.
I agree with all of your other points.
Someone thinking girls were locked in the basement and deciding to storm the place is a sign of a mental health issue. But his actions doesn't make the known facts false.
