I'm not sure why you decided to hop into this thread being rude, I'm not typically a rude poster. But bragging about how consistent you are is not really where you want to take this conversation.
Language already is legislated. Here is some reading for you:

The question was not, "Should language be legislated?" since the answer to that is that it already is to some extent. There are things you cannot say in public, there are words you cannot put on your license plate, there are songs they will not play on the radio, etc.
My initial reaction was that driving around with a massive profane sign on your car that says, "Fuck Trump, and FUCK YOU for voting for him," should warrant a fine since that certainly seems aggressively profane. I said the idea of being arrested for it was way overboard though.
After further consideration, I decided that I didn't really feel that the law should go there. I changed my mind after really thinking about it for a few minutes. It was not a big deal to anybody except for you, people responded respectfully to my initial indecisiveness. I did not hide the fact that I changed my mind, I did not hide my original post, I owned the original post and added to it.
