As a former liberal
Commiserations - I know the feeling...
Leftism (liberalism in disguise) fundamentally relies on delusions to substantiate their ideologies.
Delusion is a mental illness that cannot be fixed with reason and logic.
(I don't know how to fix it, tbh - but mockery - until a psychotic break occurs - seems like it might be a good way to go!lol....tough love, and all that..)
