It's actually not you, it's them. That's bad culture. Overstuffed meetings intended to solicit feedback are a waste of time. That meeting should indeed have been an email. Your colleague meanwhile is a time-wasting, intellectually dishonest asshole, and ideally their career should be crippled until they learn to communicate like a human being.

Good engineers know that software development is a give and take, and will fixate on crucial things and leave other things that they can live with in the name of getting along. Good engineers also respect the time and expertise of their peers.

I'm leaving my current job over this. I've been in a harmonious team where design sessions were easy and painless and there was mutual respect for peers, and now, having not being in such an environment for some years has been extremely painful.
