My longshot hypothesis: White people generally don't face the same hardships that marginalized groups face.. i.e. unable to realize presence of any glass ceiling of their fellow POC or women cohorts.
So their experience filters out candidate problems that require their immediate attention. POC or LGBT fight for their community of POC or LGBT people as they grow up facing the same problems.
White people probably don't have most of the people problems and thus turn towards Animal or Environmental welfare.
That's why I think we should go with a petrol or a hybrid car. Mileage would be so good that it will tide over the gap until we figure out how to make batteries economically viable.
