Clearly this is a man and a woman. It is obvious that anyone who believes this to be a homosexual couple is shocked by the image of two average individuals and is looking for some way to call it shocking. Claiming it homosexual shows two things; A) you are frightened by the average human form and B) Homosexuality is the best you can come up with when trying to find a reason why it is shocking. Both of those things speak badly of you in my opinion.
