I also use the retard word often. I some times watch retards and laugh on the street. Especially the REALLY retarded ones that just walk around and make loud noises and screaming.
I mean, I don't feel like a bad person. They are what they are, it's funny. Should I not laugh out of respect? Please. Be happy that I even care for you in any capacity at all, I say. To the retards, of course.
