I can understand people getting offended at Brad's post, but it was a post he made in his own private journal which people chose to read.
I do think 'public figures' need to be held to the same standards as everyone else; but I wonder sometimes if they all need to be held to higher standards. I'm willing to bet in the 120,000 or so users than at least, I dunno, 10 or 20 thousand have posted remarks that could be construed as hostile to overweight people. So, Brad posts one, and suddenly people are canceling accounts and leaving? Ok, call him on it, fine, maybe start a discussion in your community, but don't you think you're over-reacting just a little bit?
As someone who rides a bus 2 hours a day, I can appreciate the difficulty of having to sit next to someone who's extremely overweight. It might not be that person's fault (although some are rude and won't even try to make room for anyone else) but it's also not like he leaped up and screamed at her in public. He kept quiet and then complained in his personal journal.
Sigh. I'm so tired of this. Get a life, people, and if you're so easily offended, maybe you ought to learn to sit back and relax a bit. Life's too short, if you take mortal offense at everything that's said you'll never have a chance to enjoy life. I survived public school as a half-Asian nerd, and got my share of taunts because of it, and learned to live with them. Surely you can survive reading a post someone made that was directed at his friends, not at you.
That's all I have to say on this matter. For now.
