Frankly I think all children's TV has went down hill since say the mid/late 90's, but yeah slightly more on topic, I'm not agaisnt homosexuality, but in a kids show? really? yeah there's that whole "Oh but they might have 2 dad's/mum's", they may also have an extra buttok.
What was wrong with the old days where the only accent kids heard on tv was the "local" one or a generic "BBC accent" all I'm hearing these dasy is regionals from various parts of england, as a perfect example my friend's little sister was somewhat of a "late one" and has been growing up with the new millenium's kiddie programmes which are frankly mind numbing to watch. Now, to the point, me and my friend essentially grew up together watching the good old stuff "Fireman Sam Thomas the Tank Engine, Postman Pat, Play Days" anything that the BBC had really, both adapted a degree of the local accent and our parents. However his little sister has some sort of "hybrid" accent of various regional english accents along with the local Belfast one.
Now the real point, if that sort of "programming" can happen simply by watching those kiddie programmes despite all the normal strong influences, namely parents/friends/school, if homosexuality is made a "big thing" I can't say I want that, hell I knew Ernie and Bertie were "good buddies", I knew "Him" wore girls clothes, and I am accepting of all that, I don't see any need to reinforce that any more. There are plenty of silly antics of crossdressing and homosexuality in various cartoons, and if someone becomes homophobic, it's not the TV's fault.
