why is multiculturalism and mass immigration happening

Well they did ask for it actually , it's a legacy of the British Empire.

Did you like it better when you invaded their countries, enslaved their people, stole their natural resources, killed and maimed them, and then controlled who was brought back as servants?

The exchange program. First British people came to other countries, now people from these countries come to Britain. 🤷‍♀️

Wars and global inequality. Sorry, was that a trick question.

FYI, they are also people. The vast majority work and contribute a lot.

I have a telephone message for you from a Mr. David Duke. Do you wish to speak with him?

Again? The last time was 1066..too soon!

Why are you afraid of other cultures?

Those Druids must be rolling in their pyres if they could see what the Anglos, Saxons, and Jutes have done to the place!

Are you in this photograph? Asking for a friend.
