Well, it's just that people who are like that have their weapons readily available when on the internet. It annoys me sometimes when I ask for a description about a character before I decide to whether watch a show or not and all I get in response is "MOE" or "GAR", and "You should watch it for the moeness".
What I wanted to say is that I have the impression that even more people are/become mad/idiot/perv now that internet exists. Internet is presented (at least here) as a fabulous tool to become a better person, to become smart, but me I don't see internet as something only useful. That's also something dangerous imo.
And sometimes I am afraid by the things I can see/read on internet... Really.
