Ok, so I have nothing else to do, work is done, and would like to throw my $.02. Dude, Chris, Hitler--whatever you'd prefer to go by, for this situation, it's still at the essence for you to define your preference as by what you'd like to go by.
I say use any frigging name you like, including Osama or baby-killer, or whatever. Dude, it's your handle, use what you like. You may just offend people. You may just have people thinking. You may just feel comfortable with something that belongs to you, and you want to keep it.
To everyone else that doesn't like his screen name, I say this:
Let's have some freedom, here people. Let the man do what he wants to. I say that if if offends people, then GOOD! It's about time people are offended. Toughens the skin up a little. Why should one man change to satisfy YOUR wishes. I say DEAL with it however you like, but deal with it, nonetheless. It seems to me that too many people now-a-days are speaking out on being offended, insisting that the world change to make them more comfortable.
I say, f*ck 'em.
Be an adult. I'm not seeing as many of those around today.
If you must insist I'm anti-semite, anti-American, anti-mom-and-apple-pie (not to mention baseball); go ahead. It doesn't bother me. In reality, I'd argue that personal freedom (and personal responsibility) are those things that I hold more dear than someone's opinion, who frankly doesn't have a significant clue as to me or my ideals.
But, like dude says, you are pretty ugly.
