Adoptive relative is against adoption

I love all of the suggestions you've gotten here. I would also suggest having a frank conversation with your parents and let them know EXACTLY how this makes you feel. Every family has different dynamics and a lot of families have the "keep the peace and ignore" dynamic. It sounds like this is what's going on.My feeling as an AP is that anyone like that wouldn't ever be included in any family celebration or activity. Ever! And I'd have a talk with them and let them know exactly why.
