I agree that it's natural, but gays have become somewhat disproportionate in Soaps these days - it's almost as if they have to have characters from all walks of life in all soaps and they go over the top with it.
I worked at a primary school where a little girl aged 7 stopped holding hands with her best friend because the other kids were calling her gay, so I do think we have to be a little careful with how much we show. I found it very sad that something so natural as kiddies holding hands had been tainted.
So, although I don't think lesbianism is abnormal, I actually can see frodsham's point.
However, as others have said, rather that than violence.
