The world will be a better place: This is fairly obvious, but it bears saying anyway. The IT industry can be a hostile place, lets make it better not worse.
Selfish reasons:
Stuff you put out in public on the internet is permanent, things you say now will be there for your future employers, significant others and friends to discover. There is no delete button for the internet.
People help nice people, people don't help those that offend them.
As in the rest of life, don't go out of your way to offend people. Try to avoid using loaded language, avoid all the isms. It's far better to be called politically correct, than be an offensive jerk.
