some observations:
there are some Dawkinite type views on religion, spaghetti monster etc. look at them they are stupid, hahaha!
this approach wont work in convincing people and when it is applied to another minority ethnic group, it can often come across or is likely to be accused of racism and xenophobia. even if in many cases it is not that ie I don't think Dawkins is a racist, he hates religion as such, but when he criticises Muslims, it comes across as racism, 1st world privileged white intellectual from Oxbridge laughing at these stupid poor black and brown people who believe in God.
religion provides many things that secular society doesn't, and many people need these things, ie a community
also a lot of secular culture is now, frankly, borderline pornography. pop culture, ariane grande, kardashians, etc.
I'm not a Muslim but I don't like this either, and I can't say I really blame Muslims and others for rejecting 'western' culture and 'British values', if not explicitly, at least implicitly. western culture has become trash.
perhaps there's a problem not with the Muslim parents, but rather with western culture and British values.
I don't think LGBT will ever be accepted by religious people. coercion and propaganda wont help. rather it will alienate people from the society and the state.
