Gillian Tett writes a good article about how many gay business people fear discrimination and thus are reluctant to come out. Her final paragraph makes a good point though, whilst there certainly should not be any discrimination, is this really any of our business?

Apparently "Lord Browne, for example, did not reveal his sexuality by choice; he was forced into the open after seeking to suppress a newspaper’s plans to out him."

Business people are not generally public figures so they should be afforded privacy. If it doesn't affect their performance, how is it important whether someone who is gay is "out"?
