Why do some people react to others comments etc. with such nastiness? Calling them names etc?

Because some peole have no respect.

JUST SHUT UP YOU TURD BURGER

Because some of these parents here are morons. They give their daughters a masculine boy name and black ghetto trashy names. 

People are assholes and anonymity shows their true colors 

Because Lori is blunt

One man's treasure is another man's trash.

Because most of the times people ask stupid question which can be answered via a simple internet search or ask questions about personal issues and only present their subjective view of the scenario.

Because they probably feel bad them selves and want you to suffer with them . Don't let negative comments bring you down. :)

I don’t know, idiot. Shut up. lol just kidding. It’s because people are mean.

Because trolls.
