> But sure, stating an opinion is the real problem

Where do you get that? All I suggested was you express your opinion clearly, rather than euphemistically.

The way people in a society think influences the character of that society, obviously. Do you disagree with that?

If people in some society like the way their society is, more or less, why should they want to import a whole bunch of people that think very differently from them, who will make their society very different in a way that they are not interested in it becoming? How would that benefit them?

It's a really fundamental tradition of french society, going back to the revolution (or even before) that you can think how you like. If you dislike this foundational principle, then you cannot say you like French society 'how it is'. You are in effect saying you would like to change probably its most fundamental rule.

I don't know if you're using this argument to convince the 'normies', and actually you don't like brown people because they frighten you, or if you actually believe it. People often believe in self-contradictory things, but then again, people with unwarranted self-regard often think they can convince other people with obvious nonsense. Perhaps a bit of both?

That doesn't mean you have to want people who happen to think very differently to come in. You can like the fact that people in your country are free to think how they like, and also like the fact that most of them happen to like to think certain ways.

Projecting?

Perhaps you should consider that it does make sense, and you simply don't want to understand it. I don't think you're intellectually incapable of understanding it.
