What??!!??
Just because a TV presenter or a character in a TV show is gay doesn't mean it is propaganda in favour of homosexuality. Do you even understand the concept of propaganda or what the word actually means?
Propoganda is certainly the wrong word, however I do kinda agree with the point I think he's trying to make, there does seem to be a lot of gays on the TV at the minute as if its some sort of ratings winner, the same was done with female comics a decade or so ago, its nothing to do with them being better than XYZ presenter, I think they actively look for gays to fill certain demographics and employ as according.
