I think this conversation will continue in circles until everyone agrees on the definitions...which will never happen, mostly because a lot of people need to rely on flip-flopping labels to suit their arguments when they are in a corner.
The big problem comes with confusing the traits of the following;
Good guy VS Nice guy
Alpha VS Asshat
Assertive VS Domineering
Eh, there are too many others and I have no desire or need to convince anyone about anything...I know the difference and am content with it...those that don't probably don't want to or simply can't comprehend it. It would be an exercise in futility to bother with them.
I choose to end my interactions with those whom are obtuse...I guess that makes me an a$$hole!
