"Have you considered adoption?"

I'm honestly so tired of having people ask this EVERY TIME someone talks about terminating a pregnancy, even for medical reasons or EVERY TIME someone talks about starting <a href="https://glowing.com/glow-fertility-program">IVF</a>. People probably consider adoption a lot more than you think. Asking if they've considered it is probably waste of time. The decision that's right for one person/couple is the one that's right. 
There are already babies up for adoption who can't find good homes. So what is the point of telling people they shouldn't abort because "adoption is the option?" 
AND AS FAR AS <a href="https://glowing.com/glow-fertility-program">IVF</a>: Literally who are you to tell a couple that they shouldn't have their own biological children if that's what they want? Do you hunt down every couple that's TTC and tell them to adopt a baby instead of having sex in hopes of conceiving?? 
I can't possibly be the only person who is tired of the "what about adoption" comments, am I? How do you guys feel about it? Why do you think people are willing to deny the fact that children are already ignored in the system and that couples already get turned down daily? And why do you think <a href="https://glowing.com/glow-fertility-program">IVF</a> should come second to adoption but TTC naturally isn't "selfish?" I really don't understand this line of thought.
