Re: Virtual insanity
The term overwhelmingly gets used for putting someone down to make yourself look good. It's gone from insulting someone's taste in boybands to imply that your taste is better into grown up politics and hasn't become more mature. "You suck therefore I don't" is one of the highest profile and most tiresome logical fallacies in the 21st century.
And you're right, it's not restricted to one side.
