Do not let these people get under your skin
People can be very brave hiding behind their keyboard and usernames and get their kicks from dishing out "hate comments" to try to get a reaction
I think it is great that we now have a term to label these people (trolls) so it does kinda take away a bit of their power
We must accept these people are out their and separate their nasty comments from those giving genuine feedback or constructive criticism
Fortunately I can only think of one recent case of anything near trolling on this forum and once called on it they left pretty quickly
Unfortunately YouTube is probably the worst place for the kind of thing and you need to accept this reality if you are going to post a video
