Well thought out post, agree 100%
I would say the same about any couple over the ages of 50 who want to have a child - nature says no and being able to afford to cheat nature is just wrong. Just my opinion.
But by that argument IVF should be banned as thats a definite NO by nature. If people can have IVF then gay couples can have surrogates to have kids. Its only fair and as far as age is concerned there are enough women out there having kids at older ages again using IVF.
