Tom believes in something I can only describe as "pan-tribal-ancentralism", where anyone who can theoretically claim ancestry to a group that has been labelled a tribe by someone is inexplicably supposed to be on the same side of some immense cross-continental anti-imperialist struggles. When indigenous groups don't recognize him as a brother, he flips out and calls them racist against white people. But also, simultaneously, he'll say he's a Hebrew, so he's not white.
Tom is like a superposition of the most bigoted old white person, angry at all the minorities around him, and the most insufferable leftist trannie, bitching about how the society he is entirely a product of is so "evil" and "colonialist". It's like he adopted his politics specifically to piss off anybody who might be sympathetic to him.
