So you go through life ripping people down. You must be a real barrel of laughs to be around.
And I don’t see why conforming to society is always a great idea. Certain aspects of society needs people to conform, but most things are, when boiled down, not necessary.

“Yes, in a pub”
Your definition of snark seems very off. Snark is only ever used in a passive aggressive attempt to tear down another person. It is literally “critical or mocking comments made in an indirect or sarcastic way.”
Snark is never made for the edification of the other person, nor is it ever constructive.
