AITA for taking my parent's side when my brother came out of the closet?

This is exactly it. Straight kids don't have to come out to their parents and they don't have to fear their reactions. The slightly luke warm reaction of blandly telling him they accept him probably didn't really sound convincing to him, especially after he will have been working up to this moment for a while, maybe even years. Not acknowledging that is a bit of a dick move, and isn't great allie-ship.

I'm not saying this is the case here, but that kind of minimal acceptance is also a great way of hiding homophobia and then turning it around on the person coming out by saying you're treating them the same as everyone else - you're not as straight people don't have to come out - and making it seem like they want to be celebrated when in fact they just want a proper discussion and acknowledgment.
