Talking about how you’re going to keep the six fasts of Shawwal, asking about Islamic schools in a certain city/country, discussions about learning of tajweed rules, learning Arabic, asking about hajj rites certainly don’t seem objectionable to me. This is the type of stuff I came across after quickly skimming through the site.
Are the views you’re mentioning endorsed by the owners of the site or are they the views of certain participants? They also state very clearly that they would get rid of anything if it is found to be against UK law. They also state that it is a place where both Muslims and non-Muslims are welcome.
