The problem is there is no such thing as "proper spelling and grammar". By who's authority is it "proper"? The dictionary can't even produce self-consistency, let alone some sort of overall fundamental logical sense.
Fundamentally, I see nothing wrong with your string of l33t-speak (or text-speak as the kids are calling it now) as long as its meaning is unambiguous.
If "irregardless" makes you wince, how do you feel about flammable/inflammable? Also, will "irregardless" suddenly be acceptable ~5-10 years from now when it makes its way into an "official" printed dictionary like Webster's? Irregardless doesn't cause confusion, because the only people that don't understand its definition (synonym for "regardless", despite apparent root structure) are grammar nazis who refuse to learn.
Evolution is, by definition, made of aberrations.
As I said in my original post, I am a recovering former grammar nazi. I understand, to some extent, where you are coming from. They key realization for me was that an "error" isn't really an "error" unless it actually prevents communication from occurring.
I love my language too. "If you love something, set it free." If you dig in your heels and stick to "proper" spelling and grammar, you will rapidly find yourself unable to communicate with the rest of us.
