The chief executive of the National Secular Society has claimed it is "bigotry" for religious parents to protest against their children learning about homosexuality.
Stephen Evans appeared on the James Whale show to discuss the news that Muslim parents in Birmingham had pulled their children out of Parkfield Community School in protest at the the school's relationship lessons, claiming they promoted gay and transgender lifestyles.

"One thing that unites the religions I'm afraid is bigotry and intolerance of homosexuality," Mr Evans said.
"What they shouldn't do is dictate to schools what they should and shouldn't do, and what they can and can't do in the classroom."

Last week, 600 Muslim children aged between four and 11 were taken out of the school by parents in protest at the lessons, which are part of a programme to challenge homophobia.
"These opinions need to be robustly challenged, not respected. I don’t know whether they’re religious opinions or not, it doesn’t matter to me. It’s bigotry and it needs to be challenged," Mr Evans added.
"There’s a lot of misinformation out there, and the parents just need to be reassured that this is not about promoting homosexuality or teaching children about gay sex, it’s about having conversations with young kids about difference and British values."
