What are the horrible consequences of downplaying the effects of the buying and selling of women, where the typical age of entry into the life is 13?
I don't think using the word pimp is creative or colorful, just like using fag or nigger isn't creative or colorful. There are plenty of other words that can be used effectively without glorifying and condoning men who sell women.
We all get to decide what is morally and socially appropriate, in forums like this where we discuss it. People were simply using the fact that it exists in the dictionary as evidence of appropriate use. You will also find Jew in the dictionary as a verb meaning to cheat or haggle, and gyp as a verb meaning to steal or scam, but that doesn't mean they aren't words loaded with hate.
