Lots of people seem to think that "free speech" means "I have the right to say anything at all, no matter how awful or offensive, without any consequences whatsoever." The first part of that sentence may be true, but the second -- the part about consequences -- is not. People should realize that advocating beating children is an opinion that has consequences. With freedom of speech comes responsibility, and the idiots on that radio show need to discover that they have to take responsibility for their ignorant, hateful actions.
What the heck is it with Sacramento, anyhow? Rush Limbaugh got his start in right-wing talk radio there, as many people know. I was listening to him back when the only station he was on was KFBK. But I don't recall him ever suggesting that the right way to deal with a gender non-conforming child was to beat the child with a shoe.
