Either birds are dinosaurs, or they aren't. My brother says there ain't no two ways about it-- as you say, they are dinosaurs the same way I'm a primate. Obviously they aren't Composognathus* the way I'm not a lemur, but that's not what I was wondering.

*a small theropod, most probably an ancestor of birds

Avialans are part of the Dinosauria classification, yes.

The problem is that that not even all Avialans are "birds", let alone all dinosaurs.

So, yeah birds "descended" from dinosaurs, so did a lot of other stuff. I don't think anyone disputes this.
