Typing badly on the internet is like dressing badly in real life; no matter what kind of person you are, people will judge you by the wrapper, because they think that you can help it and should do a pretty dance for them.
It's sad, but it's true. People are assholes, and will not listen to you unless you learn to type well.
It's not too hard to do, although it takes practice. I think there are some places on Gaia where you can learn to type well.
