Why do people use the Internet to talk trash to people?

I just don't understand it. I see it on YouTube and yahoo answers all the time. People will write people just talkin all trash. It's like what do these kids go through everyday to have to resort to talk all their crap on the Internet? I feel bad for you guys. I'm sorry that y'all don't have the best life and get picked on. But everyone knows that's the deal when y'all have to resort to the Internet and your 500 miles away. Guys just help your selves out. It's sad that y'all have to do this. Like I'll ask a question on here and y'all just talk trash. It's un needed. I'm sorry guys. But no one deserves to have y'all talk all of that trash to em. So fill me in as to why kids do this. I just don't understand. Stand up for yourselves in person and you won't have to resort to only being able to talk trash on the Internet. Well god bless all the others. Let me know how talk feel about this. And I know one of y'all trash talkin people on the Internet will read this but leave your comments to yourself. Alright bye.
