On one hand you have the proudly ignorant and martyr complexed boomers who think they are the only one experiencing hardships or having any sort of wisdom anything, so special and unique and on the other hand you have the snowflakes who go on moral crusades and adopt faux morality and causes in a not so subtle attempt to assert superiority over others and to control them.
Full of pretenses and entitlement they go around in life trying to strong arm others into doing their bidding and try to raise above everyone due to an inferiority complex that pushes em to constantly attempt to remind you that its them that are better than you. Vices become virtues "lol im so bipolar" "im so bossy" and so on.
The easiest way to deal with this type is to treat them like the petulant children they are and call them out on their BS. A simple "Youre not very smart and responsible for having 3 kids at 18" and "You could not survive without your parents money because you are not capable of anything worth shit" might make em pout but at least it will make them shut the fuck up especially if you can get others to laugh at them too.
