The issue I have with the way some people suggest adoption (or other things like major fertility treatment, surrogacy, coparenting, fostering etc) is that it can be presented with the slightly dismissive handwaving air of ‘here you go, here’s a Ctrl+Baby solution’.
Like the person is scratching around for an easy answer — ‘here’s another way of getting a kid!’
It dismisses the level of consideration, discussion, (sometimes) compromise, (sometimes) invasive questioning or medical treatment, and forethought that goes into adopting, fostering, working with a surrogate or undergoing fertility treatment.
Not to mention the delicate and highly personal framework of circumstances that lead to alternative routes being explored in the first place.
And it betrays that the person saying it does not appreciate their sheer privilege of being able to conceive with relatively little effort. ‘It was easy for me, here’s how it can be easy for you too’.
I don’t find it offensive, but I do find it ignorant, naive and blinkered.
