I've been thinking about hate and fear a lot lately. I think hate comes mostly from fear. On these threads the fear is mostly a fear of the darkness (self imposed ignorance). Instead of trying to light up the darkness, those that fear huddle in a corner and quiver.
Near as I can tell the cause is hormonal. I recommend removing the endocrine system of everyone who is afraid (OMG I guess I have "NO boundaries").
LOL.
If I had been drinking something when I read your post you would have owed me a keyboard.
