For starters, if you can define a specific known crime being committed by a specific person. It is fundamentally wrong and you absolutely should bring it up at the right time and place. If your accusations are about groups and the actions committed aren't specific actionable crimes that you are aware of, you're very likely in politics and/or advocacy. Human decency is a very nebulous term when it comes right down to it. What I find right or wrong may not match what you find right or wrong. Without an agreed upon objective measure you can't define who is actually right - regardless of how clear or blurred the lines appear to you. Without that objective measure, especially if debate skills are bad and participants are low on listening and high on fallacies, then it's really just an unproductive shouting match.
