I wouldn't say that there are sexists on this forum but there are a lot of idiots. There are about 800% more loons on the internet than real life, or they are more visible.
Trust me there are more loons out in the real world than on the internet, just think of all the homeless people talking about the end of the world, I doubt they have the internet in their cardboard boxes.
Theres a wonderful thing called an Ignore List to be found in your profile settings
I recommend you use it to full effect
I also frequent a rock climbing website, and it's really pathetic seeing all the cyber-stalking freaks out there harassing any of the women who admit to being of said gender. They even have to remove their profile pictures due to the obscene amount of lewd and immature comments.
Anyway, No Longer Welcome means you've been very naughty, or just a complete ar$ehole
