Depends on the individual. I think for some, it's just another step of their radicalization.
It took repeated instances of reality being a battering ram against my own liberal delusions until I finally became a "tankie", until I finally realized that the system is unfixable and "civil debate" will get us nowhere.

never allow them to get away with claiming to be left because they aren't. These people are liberals and will always try to hurt the left.

. Rub their noses in it. All projection. We're not the ones supplying tanks.
