Do you think there are too many immature people on the web?

Let me say that I have encountered many immature people on the web, especially on this site. That's why I was gone for over a year. Now that I am back I had one user, I'm not saying who they are even though I should, was acting so immature to me and lashing out at me because of my beliefs. Seriously, people better learn to grow up and realize what they say isn't always right and they should learn to except that.
