You saying that as long as someone does not act on their discrimination then it is okay to discriminate, just in their mind? I think this goes without saying, but I agree. We are not going to police people’s thoughts (don’t give Elon any ideas).

However being human beings, I would also argue that this is practically impossible. If a person discriminates against a minority in their mind they will do this in real life. While there may be some people who have the mental will power to accomplish this, the majority do not.

This is why we have social pressure against people who promote hateful messages. Especially if these hateful messages are directed at minorities. This is because it creates a discriminatory environment where they can’t coexist in.

So while I do agree with your thought experiment, I don’t think it has any practical application.

I may be reading between the lines here, but I am guessing you or someone you know holds anti-minority beliefs. We often struggle with trying to explain our or others irrational beliefs.
