Non - RHH : Why do people hate so much on the internet?

I made a video of me dancing to a new soulja boy song and soulja boy
liked it and posted it on his facebook wall . It got over 1,400+ likes
but the comments are getting me pissed . There's like half of comments
that thought my vid was good then the other half didn't and thought i
sucked . I don't see how people like to do that . I actually effort,
energy , and time out of my life to make that vid . If they got there
video posted by somebody famous . I bet they wouldn't be saying
anything . I don't see how people actually love their haters . smh If
