I don't know who you are thinking about but outing should not be reserved for anyone. it is an extremely stressful situation to be placed in, and in the most extreme cases may lead to suicide. Who is homosexual or bisexual is their business, and anyone who tries to cover that up by acting homophobic tends to be under a lot of stress to hide that part of themself by creating a survival mode which they feel they can cope, and should get some help for it.
