Good luck with that, you're gonna need it. Who cares who harasses or insults you on YouTube. I will admit i was once surprised by how crude and vulgar some individuals can be toward people they don't even know but that is why YouTube wants members to stay anonymous which is why they don't put in your profile name or even your location. They are more aware than anyone that YouTube is full of some demented psychopaths who use this platform as a method of expressing how psychotic and disgruntled they are and sometimes those assholes will use random strangers to displace their anger towards the world and themself on you. Now I often expect some stupid asshole to insult me for some misinterpreted comment and when no one does I am pleasantly surprised and if they do I am often amused. Just man up and be a man about it and just laugh it off.
