I feel you. When I was in my 20s I was a bloodthirsty lib post 911. For context, I was in the 10th grade when that happened. I was not so bloodthirsty that I joined the military, but had I been conscripted, who can say? There is a reason why Bush had between a 90% to 70% approval rating at that time. Hegemony, manufactured consent, and reality building. I don't know what it is like to grow up under the settler colonial hegemony of Israel, or how hard it is to unwind that thinking. However, I know what it's like to be a disillusioned 20-year-old pumped full of rhetoric.

You can get drafted, but the conditions of your indoctrination and its power over you will determine your willingness to participate. As I mentioned in another comment, this is simply context that explains the behavior. She's had a long time to unlearn that indoctrination and, by appearances, hasn't really. I didn't find my way out of the hegemonic hedge maze until my mid-30s. I know I've said some unhinged things in my 20s that I can cringe at today, but I also know I'm not being held to account by a large audience of people either.
