The leftist Jews you see trying to ruin Christmas are the same ones who cry about how mean Israel is

Because diaspora jews also swallow cultural marxism as religious dogma when it was only meant to brainwash average white people. Like Bezmenov said cultural marxism has been taught to generation of people to think patriotism is wrong and think in idealistic way, so even young liberal jews in their dogmatic view think it's racist for Israel to treat Palestinians like that. But it doesn't matter what they think, at the end of the day, they still have a place to go back to as long as Israel stays the way it's been (But recently it fell victim to globalist hoax which is another topic for the day).

Muslim terror attacks against Christmas and Easter don't ring any bells?

They are called extremists for a reason. Beside muslims don't mean only middle eastern people, that also includes South Asian countries like Indonesia and Bangladesh, so with that many numbers of muslims, surely there must be some extremists that only revel in violence to spread their message. I don't blame muslim terror attacks against Christmas and Easter on terrorist as a result, I blame the motherfucking leaders that promote multiculturalism and brought the outsiders in while KNOWING there were radical muslims while they live in comfort with the multiple bodyguards.
