I think that's a bad decision, but I am not willing to think it's always an anti-minority thing.
There were people who had similar feelings about Boris having ties to the US.
There are people on this thread who I think were actually Labour supporters who feel that having a wife who is a nom dom he essentially has no real skin in the game in the UK. That is, doesn't really see himself as British, so much as an Indian, or maybe an internationalist.
It can often be questioned when an important political figure has close ties with another country, financial or otherwise.
