People that post on public sites but cannot take a different opinion

Seems these days people cannot tolerate a different opinion . No matter what the post is about it could be the weather, sports ,politics, porn or what some internet celeb said or whatever the topic of conversation is there is always someone is outraged over what someone else posted and want it taken down. My opinion is this if dont like others opinions then why are you on a public forum posting anyway? All over the internet this happens name the site its there

 

In internet this happend cause of trolling-meme people that think to be the God, and, when you are discussing, in internet, you can always have right, everyone become an expert because they just need to write something and they find it, then they show their sapience and feed their ego.
In real life, this always happend, we want always to have right, some people pretend this is normal, for me is a Narcisistic mask.

Anyway, in truth, i will say, let them do, if they are perfect, if they don 't make errors, if they know everything, they should not be here on the Earth but in some other realm of consciousness, ecc...but they are here and show how they are good. Let them do, don't get angry but stay neutral, if you take a side, they will slay you, but is my opinion.
