As far as taking action goes, I'm afraid that the masses are not likely to be with you; they won't understand or want to try to understand all this, so surely any pressure you seek to apply on the politically correct by boycotting their products or services is likely to be too diluted?
Of course, everyone has an economic vote but in the UK, at least, we seem largely uninterested in exercising it unless the issue is animal welfare... and I don't say that disparagingly because I'm that way inclined myself
And the only way of resisting this with our political vote would be if these people who promote all this garbage were to attain proper political power and found that they (like all other politicians) now needed those votes, which is never likely to happen and they know it, which of course is why they speak of "system change"
