Right, Doc, I'll type this slowly because I know that you're hard of thinking.....
There are soooo many children already in the care system, which itself fails them, by sheer weight of numbers rather than anything else.
Instead of staying in these grim places until they are turfed out onto the streets at 16, wouldn't it be a good idea to give them a warm, loving, safe and caring environemt in which to live ?
If gay couples can provide this, why not let them ?
There are enough women in this country giving thoughtless birth to babies which they will ultimately fail to provide any couple with a child !
