> It's a very European thing to think of the E.U. as the indispensable center of the world.

Huh? Culturally, that has absolutely not been my experience - quite the contrary.

In the case of the GDPR, it's simply a matter of "if you can't respect our citizen's basic rights, then we don't want to be doing business with you".

That has nothing to do with considering the EU to be the 'center of the world', and everything with setting the conditions for trading with it. You can either take or leave those.

It works both ways.

You are correct. That's what makes visiting another country/region fun for many people. They like to explore and encounter things they don't have available to them where they live. Otherwise, why leave home?

Decide if you talk about not giving a flying toss doing business or visiting for fun and leisure.
