Yeah I've stated before there's clearly a significant bias in the rhetoric used in the media and on socials when a far left radicalist commits a crime compared to someone on the far right which needs addressing, but the point I'm trying to make is it's literally all conjecture in regards to a direct motive at this point.
Said motive is perhaps looking clearer as more information is revealed but the trans partner is claiming they didn't have a clue about why he did this, nor his family or his friends and he's not cooperating at all.
So there's nothing really definitive yet.
