Journalist and author Yasmin Alibhai-Brown claims second and third generation Muslims are becoming increasingly "intolerant" towards other cultures.
Her comments come after Channel 4 conducted a poll for an upcoming documentary about Islam, which revealed roughly 52% who took part thought homosexuality should be banned.
"This isn't the older population necessarily," she told Julia Hartley-Brewer. "Young people, second and third generation Muslims, are becoming intolerant - and quite proud of their intolerance - even of other kinds of Muslims. Today I meet young mothers who are teaching their children if they play with non-Muslims, something terrible will happen to them. It's very worrying."
Alibhai-Brown noted this is something that has developed over the years, and it has contributed to a kind of social isolation for those particular groups.
She said: "There is almost a kind of understanding if you let this happen [Muslim children socialising with non-Muslims], then your child will become English.
"This has been the most malign influence in our country over the years in my view."
