I don't have a problem with them. The people I care about, and whose opinions I care about, wouldn't dream of using them. And as far as concerns the others, I really don't care what they think. An awful lot of people without great knowledge of the world are frightened by what they don't know, and I really don't have the time or energy to try to educate them. They're a fact of life. Always have been, always will be.
