Yes, when you scope a movement to just the thing it's about, you'll get a greater intersection of people who can agree on those ideals (i.e. actual intersectionality). If you check

very opinionated on politics, probably moreso than almost all people (he has multiple things he writes about across the world every single day going back decades and maintains a list of assorted topics that mostly have nothing to do with software where he thinks we should change the law[0]. He's encouraged many boycotts over the years, and goes way further than most people to stick to them), but he wisely kept that movement focused on the thing it was supposed to be about, and in doing so was able to actually accomplish something.
