Very true. At the same time several pictures of him show him wearing vaguely "conservative-style" t-shirts....things with USA flags, etc. At shooting he was wearing Demolition Ranch t-shirt (popular youtube channel that while not political is certainly strong 2A supporter).

I have no idea what any of that means....being non-conspiratorial he appears to be like any other non-ideological young male. Vaguely pro-america with middle-of-road political beliefs that also supports some ACTBlue talking points.

Just doesn't seem like that would be a "highly motivated assassin".

Like you, the lack of any known social media is puzzling....I just don't think an average young person gets that extremely politicized without arguing about politics all day on internet.
