why cant i get 100 points?
There is only one way to lose points...by downvoting people. If you down vote, you loose a point. The reason it is setup that way is to keep people from downvoting all the time. Apparently you didn't realize this. To give you a hint, click on your point total next to your name and you will see a history of ALL of your activity. you will see you have downvoted many arguments. That is why you hover near 100 points.
Dude, I hit 100 points in a single day. I invite honest debate, and I tried to avoid upvoting OR downvoting on my own debates as a matter of principle. Now I find out that's a really good thing. Also you're rude and a bit of an ass. If you're smart i can't tell because it's obscured by your obnoxiousness. Just sayin' ;)
