UK bans people for what they say

The U.K. doesn't have to let anyone into their country if they don't want to

That's my point.

Now if someone pays taxes and/or is a citizen of a particular country, then I could see how they'd expect to be let into that country, but otherwise I don't see the argument.

saying someone shouldn't be able to enter the country + getting mad when someone says you shouldn't be able to enter a country = irony

Agreed and kinda funny.
