Ism's

We got in to the discussion in class today about all sorts of -ism's. For example, there is racism, feminism, abolitionism and so many more. It seems that lately every word can be completely correct and have an -ism attached. What extent will this go to? Everything that has an -ism is associated with being bad. For example, racism. This everyone knows is a horrible thing. No one wants to be accused of having racism. But, when will words stop having the word -ism be put at the end to associate terrible things. -Ism's have been around for a while, a long while, but will there ever be an end or will there become more of them?
