A preacher in the UK got arrested for saying loud enough for others to hear in public that homosexuality is a sin.
From what I hear and read Muslims are at least as much against homosexuality as fundamentalist Christians and the countries that still list homosexuality as a capital crime are Muslim dominated so I have no doubt that the police have had complaints.
The UK is pretty bad when it comes to freedom of speech as they have laws that allow them to arrest you for causing "harassment, alarm, or distress".
I would think that would allow them to arrested me for a pro-Bush, or anti-Obama bumper sticker.
Makes me wonder what they talk about in the UK (if they want to stay out of jail).
