British practiced a same methodology to keep the natives away from the countries they ruined to feed the mouths back in UK. Lots of history books testify the presence of boards stating “Natives Not Allowed” in India, Africa, …. etc. So it’s another version of a Great Britain’s (I really don’t know what’s great about Britain now, and still they call it Great Britain) contribution to the world.
Just don’t complain about the local customs. If you don’t like the country or the customs, simply get out, go to your countries and live happily.
