I doubt Mr Munroe and I would actually disagree in principle on many political issues. But even when your cause is just, your argument can never be “my voice is louder”.
The thing every angry, morally-fired-up idealist misses, is that this isn’t actually a more enlightened age, because objectively there is no such thing. Your grandchildren will consider you just as awkward and outdated and “problematic” as you consider your grandparents, never mind how progressive they were in their youth. In five hundred years’ time we will be considered exactly as barbaric and misguided as people who enslaved each other and stoned adulterers to death, for a whole new set of reasons and cultural preferences. Every generation thinks the past was morally wrong.
And none of them are any better than the others. Oh, look, look at our rights, look at how permissive our culture is! I agree, of course, but that’s because of the age I was brought up in. Open a hole in time and we would find cultures that would find our social ideas exactly as horrifying as we would find theirs. Which of us is right? What the hell does “right” mean?
Ideology is one of the many, many, many tools people use to gang up on other people and beat them up. Fair play, even-handedness, the courage to be different, and tolerance for diversity are the only consistently laudable characteristics through history.
Self-examination is difficult. Going against the grain is difficult. But if 99 people say it has to be one way, for no other reason than they feel it’s so, I reckon you have a moral duty to voice the suggestion that it’s the other way.
