"Potent" was probably a bad choice of words. "Passionate" would be more accurate. In the political arena there are often causes that have little passion behind them, like feminism, and used only for cynical political reasons. On men's forums you hear the full range of true oppression and that causes people to be passionate about the issues. It's "needed" in that the oppression is being suppressed and there are true "victims" of this the most powerful interest group in America...feminism.
