It’s not that liberals believe in nothing. It’s that liberals have a very contradictory world view. They want peace, love, decency, etc. but not at the cost of actually changing the status quo.

As other users have said in this thread, liberals are actually white/western supremacists who think they are loving and tolerant. So the vast majority of their beliefs amount to nothing in the end because they have no desire to remove existing power structures

It’s also why liberals always get rolled by fascists. They think fascists want to play by these silly social niceties and therefore legitimize hateful and down right ridiculous ideas from fascists
