This reply is an example of exactly why people don't want to discuss things like this at work. People rarely want to have such a combative discussion with our coworkers, especially when framed as an all-or-nothing, very high stakes conversation.

If these issues, such as where you use the toilet, what you wear to work, what documentation you are provided, are relevant to your work-place, I would suggest that they are not "political" topics, but instead workplace topics and could, and should, be broached. However, I don't know GitLab's stance on this.

That being said, I do agree with you that all of these things are political, as well as who is causing the issues. However, your coworkers might not, and there might be very good reasons to continue to work with such people.
