It's easy for people to cherrypick with groups.

There are tons of antisemitic leftists. I've had to heavily curate my social media because of them, and I'm lucky because that's all I've had to do (eg, I'm not being chased across college campuses or doxxed for belonging to a synagogue or have people waiting outside of my door to hound me immediately).

But there are tons of leftists who aren't as well.

Leftism has become co-opted as way for people to virtue signal and rationalize things they want to believe. The right is definitely seizing on this strife. But historically, there's nobody the left likes to fight more than other leftists.

And the meme at the top about immigrants... that isn't new. The USSR was famous for establishing ethnostates and it carries over to modern day. Sure, you could immigrate. But it isn't like workers held hands and ignored the differences. The pressure was there, but perhaps not the wage pressure. Out groups were still blamed for things like shortages and service degradation, just like today. Nor a defense of anti immigration, but people seem to think the problem exists in uneducated or unenlightened people close to be leftwing. Nope, it's our cohort. We are watching it in real time right now.
