When I can, I try to point out “hey, we need to caption this” or “hey, I’m not sure this is accessible to visually impaired users” or “uh, these gender options suck”. Probably wouldn’t bring up my personal identity unless it was somehow relevant, which it rarely is in these kinds of discussions. I think it would be inappropriate to have a discussion about broader politics (“hey, what do you guys think of the bathroom bill?”) in this context — the thing that personally drives me up the wall is water-cooler conversation about politics like it’s a sport, when it’s unrelated to the product or the company.
