Shut that door!

A report commissioned by the BBC has recommended that the Corporation should put more gay, lesbian and bisexual presenters on children's TV programmes.  And this is not recommended in the spirit of equality amongst would-be presenters, but so that children should be introduced to "sexual diversity" in their early years.  But what I can't understand is - how are they going to know?  Are presenters going to have to hang a sign round their necks declaring themselves as gay, straight or whatever? Other than that, it's difficult to see how you demonstrate your sexuality while introducing cartoons or suchlike.
