In fact, I think the war in Iran is a stupid and immoral thing to do. It's possible that the person you are responding to feels the same about the Israeli government's genocidal actions in Gaza.
However, you did not bother to find out. When you judge someone before knowing them, it is called "prejudice". Pre-judging.
But you can see why the Gaza response made sense? It was completely irrelevant to this discussion. I’m not sure how you’re missing the heavy sub text here.
The report notes that both Hamas fighters and regular Gazan males participated in the rape and mutilation of Israeli hostages.
We can think ill of the Israeli state without jumping to "fuck you for living in Israel and having nice things" as soon as someone mentions their city name.
I hope your friend over there is doing well, and hopes for peace as much as we all do over here. Maybe then we'll see an end to all this.
