But for most people I think it is usually worth an attempt at least.

You are probably right. I have an issue with conflict--I don't like it, so that interferes with my willingness to debate hotly contested subjects.

I should add, if there is a real challenge, something that must be done, fought for, I can do that. I have done that. I'm a good ally in a tight spot. But arguing, it I just don't enjoy it.
