Well you could say a child needs a mother and father BUT what good is it if that child has their straight parents abuse them. Is that essential for a normal and healthy upbringing. I dont think so. Or a child could be brought up in a gay family and be loved and cared for. Its all about the parents and what they are like not what sexuality they are.
I barely have a dad, I was manily bought up by my mum and I am normal and was well brought up. Having two parents wasnt vital for what I have become. i doubt I would have been any different if my dad was around.
I think gay couples should be allowed to adopt
