Every time you hit 'post' with a typo still at large, you think you're about to get ridiculed as much as a Diana Gabaldon quote on fandom_wank. (Weren't on the fandom scene? Read more HERE.)
But now I'm back blogging, debating, and commenting - though not on YouTube. It takes true bravery to dip a toe into the pit of ignorance and illiteracy that is a heated YouTube comments section.
I think it's that when you're in a good place mentally you're better able to put things into perspective. If somebody online thinks I'm wrong and calls me an idiot, well, all I have to do is prove that I'm right (99.99% of the time ;) and call them an idiot in return, should the fancy take me. If I can't be bothered, or if the idiot calling is likely to go on ad infinitum I can just log off and get on with my life. I don't need to spend time agonising over what a stranger thinks of me based on a two minute exchange on some internet forum. In the scheme of things, it just doesn't matter.
As Cracked (self billed as 'America's only humor site') notes -
It is said that opinions are like assholes: everybody has one.
