Obviously it's an extreme example but many of the norms of a Western mindset would be no less offensive to billions of people in this world.
What bias of moderation exists is that you probably wouldn't migrate to Saudi Arabia unless you were already mostly ok with their values.
And if e.g. economic opportunity drove you there you'd probably keep your opinions to yourself, but it's unlikely your values would fundamentally change.
I will only add - I speak from experience here.
