//If Tim were the leader of the DUP, or a UKIP councillor whilst his beliefs would be slated, it wouldn't be a serious issue in terms of his relationship with his party and his faith.//
I'm not sure I agree, sp. When UKIP were still relevant, they were constantly getting exposed in the press for homophobia/racism. And quite rightly. Homophobia should not be acceptable in a modern society.
Also, I agree with AOG. Prominent Muslims are not sufficiently challenged over their religion's disdain for gay people, and they should be. Sadiq Khan, of course, was asked about it prior to the mayoral elections, but as a general rule of thumb I think the point about disparity does hold up.
