Yes, there are some underlying issues which seem rooted in conservatisvism or rather its expression in modern politics.
But activism is not only about informing, it’s about pressuring the ruling class. And the more people support it, the better it works.
The ruling class was against civil rights, women’s rights, freeing slaves, Mahatma Ghandi, and so on. They were not convinced by facts, reason, or science. The people who are convinced by these need to show politicians that they are willing to stand up and protest if they don’t listen.
