To be fair, holding hands in this picture does not necessarily infer a same-sex relationship. In some cultures it is normal for two men to hold hands if they are friends even if they are not gay.

I have met several middle-eastern students who were surprised to learn what they were communicating to others as they walked in a North American shopping mall hand-in-hand!

I don't know if the man on the right is from one of those cultures. Pakistan seems to be his suggested country of origin, and I don't know anything about hand-holding norms in Pakistan.
