That's not really how it works.

Gemini tells me that for thousands of years, the swastika was used as "a symbol of positivity, luck and cosmic order". Try drawing it on something now and showing it to people. Is this an effective way to fight Nazism?

I think it's brave to keep using em dashes, but I don't think it's smart, because we human writers who like using them (myself very much included) will never have the mindshare to displace the culturally dominant meaning. At least, not until the dominant forces in AI decide of their own accord that they don't want their LLMs emitting so many of them.
