"So "lame" is better than "gay"? What is your reasoning behind that? I thought lame was derived from a group of people as well."

From Dictionary.com:

lame
1  /leɪm/ adjective, lam⋅er, lam⋅est, verb, lamed, lam⋅ing, noun
Use lame in a Sentence
–adjective
1. crippled or physically disabled, esp. in the foot or leg so as to limp or walk with difficulty.
2. impaired or disabled through defect or injury: a lame arm.
3. weak; inadequate; unsatisfactory; clumsy: a lame excuse.
4. Slang. out of touch with modern fads or trends; unsophisticated.

I think those last two definitions fit pretty well with that use of the word. "Lame" is not derived from a group of people. A horse that has thrown its shoe is lame as well. The word is applied in many ways, to many objects, and it is the inanimate ones -- such as concepts, ideas, or as the example in the definition shows, excuses -- to which I was referring.

The word "gay," however, is not used in a way that is referring to its original definition of "happy." If you are describing something as displeasing to you or bad you wouldn't say, "Man, that is so happy." It has acquired its slang use as a secondary insult to the gay community. And it is this use of the word as a casual insult that should be stopped whenever possible. The word "gay" is a great word. The manner in which many people use it nowadays is not.
