Bottom line is any bear is a wild animal, one that has the power to put a hurting on you in a hurry.
I'm always going to air on the side of caution personally, if I feel threatened I have no problem defending human life above any animal.
Just like if a deer/elk/what ever runs out in front of me at the last second ill mow it down every time vs, swerving and potentially rolling my truck.
But hey, that's just me.
