Often, when you get angry at people who disagree with you, it's an indication that, at some level, you have a nasty feeling you might be wrong.

Another thing that makes people lash out is when they feel trapped.

A third thing is when you feel betrayed.

And a fourth thing is when you feel frightended.

I suspect all four of these are in play at present. Perhaps more in the States than back here in Europe - that would be to do with being the chief actor in this drama, and about the only country in the world where being in favour if this war is seen as a patriotic expectation.

One aspect of the war that must particularly make people feel frightened and trapped is that, most unusually, this is a war that can't end the way almost all wars end up, with a deal cobbled together, and a readjustment of some troubled areas of conflict, and essentially the same people staying in charge on both sides.
