These people can’t get it through their heads that anyone who is offended by the British uniform shouldn’t be allowed to enter Britain.
Someone who is offended by the uniform or the national flag is, pretty much ipso facto, a security risk.
You should only allow as immigrants people who admire you and want to be you. And you should only admit them in numbers that can be easily integrated and assimilated.
This isn’t that difficult to understand.
Reminds me of returning from Vietnam......
