Except it isn't actually a sexual reference. Clearly you have your own issues if you think it is.
Plus in the context of British TV it's barely even a reference. Hollyoaks is on only an hour later with a big childrens audience and has gay storylines pretty much non stop and is more explicit in terms of all sexuality than nearly any other programme broadcast before 9pm in this country.
Plus Grange Hill and Byker Grove used to address these issues and far stronger ones, and they were shown after Newsround and before Neighbours - so between 17:10 and 17:25.
Good point - I'd forgotten Byker Grove despite watching it every week when I was younger!
There's also As If which used to be shown Sunday morning/early afternoon - as is the Hollyoaks omnibus come to think of it.
I don't remember As If. I do remember watching Grange Hill for years, they focused on drugs, being gay, sex in general all sorts of "adult themes." Didn't watched it for years and then watched a few of the last series and it was watered down rubbish. Complaining about any form of sexuality in Sarah Jane or Doctor Who to me just seems stupid and given what CBBC used to broadcast, pretty backwards.
