So many of these people have an ideological investment in a fantasy version of Israel as a virtuous democracy committed to peace.
It is a fantasy which has increasingly become a farce in light of Israel's own actions, over decades.
I don't know what psychological need this fulfills for them. A lot are just racist and Islamophobic. But they become irrationally angry defending it.
All that "reality based community" stuff goes out the window.
COPS GOOD. PROTESTERS BAD.
Like any conservative.
