Loopy theists are at it again.
This was put on a billboard in southwest London until the Advertising Standards Agency forced them to take it down. They have some disgusting arguments defending their position, but they're completely undermined by the most recent Social Attitudes Report, showing only 32% of people think homosexuality is mostly or always wrong. It doesn't help their case that they're morally backward too. To refute the majority of their argument would suggest that they have an argument, when they don't.
