This intense focus on homosexuals within the Muslim and Christian communities seems to be part of an agenda by the media. If you want to learn about homosexuals (gays and lesbians) and Islam why not simply just ask the questions to an imam - no need for cameras, a debate or a huge fanfare. Once you've asked and received an authoritative answer then move on - no need for any commotion.
As for this BBC3 'debate', the BBC has denied having censored it:
The makers of BBC3's Free Speech have denied censoring a debate about being gay and Muslim, saying the topic was pulled because of security concerns after threats were received by the mosque where the programme was filmed.
