from time to time I visit different message boards. This is unique ability to communicate with people, with whom you hardly will be able to talk and discuss some things in real life.
I was at
nazi message boards,
islamic extremists portal,
police club,
hip-hop message board
While talking and argue with people of a diametrically opposed points of view, I can compile full-fledged opinion on different subjects. it is very useful and interesting, even when talking with extremists and racists, just to find out the way they think, their basis, and their logic (or, in many times, absence of that logic).
