As much as the schadenfreude is delicious, the thing to remember is these people betrayed are truly hurt and angry. Welcome them to the tent, help point their rage at the enemy - not just Trump but also his enablers (eg Fox). "We know, we understand, now help us fight."
They're hurt and angry because it affects them, they don't give a shit so long as it doesn't. The next gobshite who comes along with ideas that fuck all of us over but helps them or seems to, they bow. So no, don't invite them into the tent, direct them to a short pier to take a long walk off of.
This stuff single handedly gives me life and hope. The revenge is epically fueling....but its also cathartic bc its meaning that for every story that comes out of people's faces getting eaten...they're fking waking up FINALLY. Wake tf up and look up at the puppeteers doing the shit.
No as soon as it no longer affects them they will go right back to the hateful shit they were doing before
