How can you tell?

Are these two gay?

A group of guys have been busy discussing on Facebook whether a certain male TV Weather presenter was gay. Firstly it's really none of their business. Secondly how can you tell whether (no pun intended)  a TV weather presenter bats for the other team just by watching him present the weather? Are these guys pshycic or something. Two males holding hands, kissing etc in public are more likely to be gay (bent, queer) than a guy presenting the weather forecast. These FB guys will then argue.....look how he dresses. I know men who are straight as arrows who wear pink shirts and pink ties. Look at the one rugby match at Durban where  the entire team wore pink in support of breast cancer awareness. Some guys presume that when a man dresses up in woman's clothing, he's gay. Well that is not entirely true either.......trust me! With that said it would be interesting to hear your views and comments on the matter.
