I don't think it takes a revolution to make a social safety net, ensure good education for every child, and institute free healthcare for everyone, but that probably sounds too close to "socialism" for some people's comfort.
Trying to 'unbias' (meaning a calibrated, countervailing bias actually) at the other end of the funnel, where incidentally 80%+ are already super liberal, doesn't really get the same mileage.
If people are primarily upset about general societal things rather than clear cut workplace discrimination, I would submit they should focus their activism at those societal things.
