Restriction on membership is a thorny problem.

As much as we dislike the fact that a club might restrict people we champion, and in the case of the BNP only makes sense in the context of racial discrimination but.....

Private members clubs have sometimes good reason and the danger of making exceptions in law rewards only the lawyers.

Would we expect the Mothers' Union to expect the inclusion of the Jewish, Zoroastrian, and Muslim faith? It is a Union based on the Church of England. TWG and WI similalry are gender based.

I once applied for a job at a Christian Book company. They were not allowed to insist I was a Christian, but they were at pains to point out that there would be mandatory prayer breaks instead of tea drinking. Maybe I didn't get the job because I only drink coffee. My devout Atheism was never discussed.
