In addition, I don't know how long her brother has been dating the mother of the child. Marriage is not the end all/be all, but the child of a girlfriend is world's different than an adopted child.
It sounds as if having adopted children is a personal sore point if a completely unrelated comment on an internet forum is this bothersome. I know that if my child were adopted, I'd not give that comment a second thought. Certainly would not be offended by it.
ETA: to stay on topic, I don't get disappointed over gifts. I'm happy with anything someone wishes to gift me, and if they just give a heartfelt "happy holidays!" or a card because they're cash strapped, that's fine too. Holidays are about togetherness for me, rather than gifts.
