The rule that I was talking about is this one http://www.penguinmagic.com/discuss/viewtopic.php?t=88983
This thread states explicitly that the type of slang, or "writing style" that you are using is forbidden. Simply, it's disrespectful, and shouldn't be tolerated.
As for your "fact," it's actually quite wrong in the way you are using it. Excepting the way you type, because you're too lazy to actually spell out words, and use some what proper grammar, is not about tolerance. This has nothing to do with excepting people, or being tolerant. This has to do with respect, and making the forum read more smoothly. It becomes increasingly difficult to read posts from lazy people. Meaning, they won't get the help they need, which usually leads to them bashing or spamming.
Trying to make this into a prejudice issue is simply illogical, as well as ignorant. It's a lame attempt to try to cover up for you being lazy. But since you are looking for facts, here are a few facts about typing correctly:
1) By using correct grammar and spelling, people will respect you more, and be more willing to help.
2) People will take you seriously, and thus help you more.
3) You will be able to actually get hired as a magician, or any job for that, if you use proper grammar. If you use the type of "style" you do now, for any job/school application, they will throw it away immediately.
4) It will allow people to understand what you want, instead of having to guess.
The list goes on, but I think you get the point. And if nothing else, you now know that it's against the rules to use your "style" of writing on these forums.
