Same boat here, a few years in Boston has made "wicked retarded" the one that slips out the most.

I used "Indian Giver" one time and I jumped on by the language police. I always thought it referred to how the White Devil would "give" the Indians stuff like the land they already owned and take it back but evidently it's about Indians acting just like White Devils and is offensive. I don't think I ever used it again.

I still use queer in the traditional sense of the word and am not giving it up. In an example "I had a queer feeling of deja vu when the bloody clown emerged from closet holding the ferret." I don't accept that the word can not be used in the sense that it was used for a few hundred years because it's become a substitute for homosexuals in both a laudatory and derogatory sense. It's easier to get rid of gay, retarded and fag when they were always derogatory but a good honest word like queer is one that I have trouble censoring because it's connotations in my use are completely harmless, there is no negative energy bundled up in it's use to red flag it for me. I think if I naturally used the word gay to mean happy I'd feel much the same way.
