Excuse it? No, I'll excuse people wishing it. Certainly any attack on Israeli civilians is despicable and generally counterproductive.
Right. You've exposed yourself as a horrible human.
If you ask people in Israel about Palestinians, you'll find that a huge chunk of them share that emotion of genocidal bloodlust.
It's an extremely human reaction. Something hurts you, doesn't really matter what it is. You'll want to get rid of it.
Most people do not extrapolate from "this person hurt me" to "I want to eradicate every man woman and child of that person's ethnic group."
You're insane.
However, it's an absurd misrepresentation of my position, and the fact that you have to resort to it proves the futility of your position.
It's not "this person hurt me", it's "this group of people hurt me".
