I love your walls of text, don't ever apologize for them :) That was very well thought out and concise. You are 100% correct about a lot of things particularly the part about text getting people in trouble. I have had some bad arguments with people via text message that would have been avoided face to face or even on the phone.
However, I do believe that the world is becoming overly PC and not just about racism, but about anything. "just for men" hair products will have to change their name to "just for people" or something and that wont be enough.
Oh, and it was lame for Roseanne to try to blame her tweet on Ambien although, have you ever taken an Ambien and tried to stay awake? Crazy stuff happens. :)
