I think this is depending on how you see it. The modern landscape with social media makes activists very effective in creating information campaigns that raises awareness of how to be polite in a modern world. Eg. nowadays personal pronouns are complicated business but finding out and respecting individuals chosen pronouns are considered polite. A successful change of culture that increases empathy and respect of fellow humans in general. But the downside is that the opinions of the people who don't want to be polite in this way are also amplified and they may want to resist and pushback that triggers them to be contrary and act with less empathy and politeness to make their point. The thing is, positive changes in culture usually last and backwards reactionary people die so that makes me kinda hopeful.
