Re: Freedom of Speech....
So you are going to send profanities to someone for the sake of it?
I know quite a few people who do just that. Their speech is peppered with profanities every other sentence, not usually directed at anyone in particular. I don't like it, don't let my kids around them, and try to avoid them myself, but hey they've got a right to speak that way if they want.
However if you think you can go about saying whatever you want with impunity try swearing on a street in the UK but don't be suprised if you find yourself in a police cell.
As for insulting the monarchy, don't do it in some European countries otherwise you will also find yourself in a police cell.
Both examples of why you just think you have freedom of speech. Insulting the monarchy in particular (or government in general) is one of the things the guys who wrote the US Bill of Rights had in mind.
Think the US is any better, try defiling, defacing, insulting or even satirizing the US flag and see where it could lead you.
It's not illegal despite several efforts to outlaw it. All laws prohibiting the desecration of the American flag were invalidated in a 1989 SCOTUS decision (Texas v Johnson) and again in a 1990 decision (US v Eichman). At this point the only way to make flag desecration illegal in the US would be with a Constitutional Amendment, and none along those lines has ever passed the Senate. You don't get arrested for it, as evidenced by the fact that people are posting YouTube videos of themselves stomping on it or burning it and aren't in jail. Do it in the wrong crowd, however, and you are likely to wind up paying a visit to the nearest ER.
There is one particular exception to all the above in the US: Cops get special protections. If you cuss out a cop you're going to jail. All the more reason to treat them with the respect they (usually) deserve in my opinion.
