You seem to mean something entirely different by polarization and depolarization. As long as the issue is polarized, then it gains network support from the issues with which it is polarized. That process of standardization that you describe as "winning" happened because the issue became decoupled from stances on other issues and was no longer predictive of other views. To put this in more concrete terms, I am not saying that you should not challenge racism and racists. I am saying that in pursuit of that goal you should actively push back on assuming someone is racist because of their political views.
