I would argue that being left handed is almost a disability. Ever talk to the left handed kids at school, a school designed for right handed kids.
But I never used the word disability. Left handedness is a malformity, as the vast majority are right handed.
But just like being gay, being left handed is not an implication of being less than. And just like being gay, the reason for being left handed is located within the physical/chemical makeup of the individuals brain.
What pisses you off more, me bieng a ex-junky that has achieved more succus in life than you, or the fact that you always fail when you try to make a point countering mine (which means I'm quite a bit smarter than you.) because you really do make some bad points, even when you put words in my mouth, they still favor me in someway if they have any impact at all.
Does your wife know what a failure she married?
