Social De-evolution?

I was recently looking at a group on facebook in which people were voicing their opinions on arguably the most contradictory subject of all, planned parenthood. It seems anytime someone voiced there opinion whether for or against, it was immediately followed by someone disagreeing, and then insults toward the person. I understand disagreeing with someone but insulting them for voicing their opinion? What has it come to in which people can't even speak without enduring mental stress? This is going to be the leaders of the country in twenty years. Are we ready?
