It isn’t always the case, and I have personal friends who were once leftists and have repudiated it root and branch.
The young woman you described is not one of them...she is still a leftist, and is what I call a “locust”...they eat all the crops where they live without giving anything back, then fly to another place where there are crops to eat. They are leftist scum.
Locusts!!! That is a perfect description of these people!
