Too little specifics here to provide on-point comments. So a general approach is all I can give at this point.
It may be you see most things as a Test of Wills. Someone has to be right and that someone is you in most cases. Anyone who thinks different NEEDS to be controlled by your response. I admit, this may not be at the root of your worry but too often we do feel the need to prevail.
In life, there are not many situations where this old man feels his Will has to prevail. Few people ask or try to require me to do or say something that is illegal or immoral, or just plain stupid in my view. So, if they are NOT requiring me to do wrong, let them have their opinions without retort.
If I feel the need to voice my opinion I try to remember that we are called to be Christ like. Would Christ feel the need to lie or say something mean? I do have responsibility to respond as kindly as I can, controlling my desire to say mean things.
One analogy is Golf. We may know the rules. But we also know some players play better than others due to natural talent, practice, experience. It is not simply not right to be quick to criticize one who cannot play as well as we can. And it is wrong to try do that in a mean way. My point: although we know better can be done, doing better is harder for some than others.
Bottom line: We are not required to respond to every “wrong” approach to us. In fact we can and should ignore most of them. But if we have to respond, first be sure you have enough facts, and in context, so you response is appropriate and then respond with kindness. IF you cannot do that, walk away.
Again just general comments on how to approach situations.
