The reason is, overall, culture, & the socio-political tribalism that's in it. But what is influencing our culture & what is the cause of socio-political tribalism?

5: Many American liberals not only hate Russia (not that I like Russia myself), but also, just as their right-wing counterparts, try to defend their team, & support foreign interventionism & even outright warmongering under a "humanitarian" label.

1: Russia has been demonised in culture as being "the bad guys" since the end of World War two, even though things have gotten better since the collapse of the Soviet Union.
