Oh come off it.
If a male forum posted a thread called "isn't she beautiful" about Martina Navratilova for her 50th birthday, I wouldn't give a shit. No one would.
That's not objectification.
It's far more likely that it would be a picture of some tennis player barely out of her teens and what they would like to 'do' to her.
It wouldn't be a female football player at all because the women get far too much abuse from male sports fans to start with.
It's offensive to even compare the this post with male objectification of women. It's pointing one aspect of a person in a respectful way. He's a handsome guy.
