I agree with you. Really it is something that probably can be learned over time. I think it helps a lot to just remember how much money this or that dumb hater have paid for their entitlements (i.e. nothing), which -at leas in my eyes- emotionally reduces their words to a child's tantrum.
Sure, but it helps more to realize once and forever: all the shit anybody says is just a "child's tantrum". Real grown-ups don't behave this way, too many people just don't grow up as they age.
On the other hand, we should also understand that a constant stream of insults, contempt, and general negativity around every step one takes, can and will bring anyone down, and even induce depression
