Without more context I'm gonna assume the person in the screenshot is a fascist. The 4chan reactionaries are split in regards to Israel. Half of them think Israel is ok so long as Jews stay there, the other half are the actual antisemitic anti-zionists.

the person who took the screenshot (could be op could be someone else that op stole the pic from) wrote the post, because of the time, not a regular user of 4chan because of the space between the ">" and the word, usually they call you a slur for leaving a space between them.

This isn't 4chan, the UI doesn't look like this there. This greentext is most probably fake, key give away are rounded edges everywhere.

I've noticed a change in 4chan over the past few years.

Years ago, the Fascists won on 4chan. Fascism became the default position. So, if you want to troll 4chan, make people mad on the Internet, and bait reactions, you post Communist stuff on 4chan.
