You’re wrong in your assumption that people who take the high road are looking for a “win”. That couldn’t be any more opposite from the truth, people who take the high road don’t care about a “win”, they only care about doing what is morally right or wrong.
I don't think that's true. People who take the high road purposefully don't care if they win, hence why they don't stoop down to the opposite persons level. 
The opposite of not taking the high road is to stoop down to the level of the person who is acting improperly. 
In my opinion taking the high road is the way to stop adding fuel to the flame, which is much better than just being petty back towards someone. Taking the high road can literally mean communicating with that person why what they did was obnoxious/ not right. It doesn't usually mean just tossing the problem aside, it means being the more mature one who doesn't need to "win"
