> I’ve been told that someone in leadership described me as being too “black and white” in this area, but I consider myself both pragmatic and flexible to alternative ideas.

When I've seen responses like that in the past, it's often somebody who just doesn't want to listen to any complaints, for various reasons. I recommend a quieter approach, where you don't tell anyone what you really think about the problems, but just wait for an opportune moment to ask "can we do X for Y?" in a public forum. That way you can't be ignored, you aren't complaining at all, and somebody else can later take credit for implementing your idea, without them having to admit that they were the cause of the problem to begin with.
