To each their own I guess. This sounds like really motivated reasoning, in that you started with the end you want and then worked backwards. Right now, your hope is that the shooter is actually a fan of Fuentes despite being in a transgender relationship, despite being on the more extreme side is saying he’s doing it because some hate can’t be negotiated out (implying that he’s actually calling for more hatred and naming it as such, which most folks on these sides don’t do) while ignoring his parents claims that he’s getting more into Left wing politics.

Or, y’know, a kid who intended to get away with it, wrote some memes from a semi plausible group on bullets in an attempt to blame the Far Right.

I’m not saying your version is impossible but it does beggar belief. It’s like when my uncle defends trump and invokes all manner of wild conspiracies to do so, what he’s saying isn’t impossible it just requires a bunch of wild coincidences etc.
