Your exact words were "I personally have never thought standing one's ground was a behavior I valued, even in a verbal altercation. To me it just looks like stubbornness, which I see as negative."
Not speaking on your behalf, but based on your subsequent comments I think you'd probably amend your earlier one to say "there are times to stand your ground and times not to stand it." If so, I won't argue about that. We'd agree on the principle, if not every application of it. Fair enough?
Closer, I guess.
Note the word "never" in paragraph 1 above refers to how often I've thought I valued the behavior in principle
of standing one's ground, which is not the same thing as thinking "there are times to stand your ground and times not to stand it." One is valuing a principle (or in this case not valuing it), the other is a judgment of the rightness of an action. S-y-g is a principle I do not value highly, and to demonstrate that I could go way off topic and list a dozen principles (or behaviors illustrating those principles) I value more highly.
But yes, you found where I used the word "never." On reflection, I'd say I can stand by it because I'm talking only about my own thoughts which aren't known by anybody but me, and I believe I made a true statement about them.
That aside, could I agree with your wording "there are times to stand your ground and times not to stand it?" as a statement applicable to other people? I suppose in the universe of all events, it's possible there could occur a time for standing one's ground (and I'm assuming we aren't talking about verbal altercations, nor when under military orders). I can't remember reading any examples you gave over the last few months where I thought standing one's ground was unequivocally the best choice, but that doesn't remove the universal possibility in general. The most likely places I might agree could involve defending children, but I'd still prefer to consider all possible alternatives to traumatizing them by causing them to witness a shooting.
Making statements about the universe of all possible actions isn't very useful, but that doesn't mean we don't make them on a regular basis.
That's the best I can do with regard to agreeing with your statement, but logically, it's a yes. So, fair enough.
