People who think immigration is something that has only happened in the last couple of decades, need to educate themselves
This country has been multi-cultural for Centuries, Millenia even.
This “British culture” people bang on about is a hodge-podge of wider European traditions. No culture (unless they have not been exposed to outside influences) has developed in isolation.
We have always been a place of Refuge, for people suffering religious and political persecution. Economic migration is not new.
…and maybe if we hadn’t invaded large parts of the world and imposed our langague, laws, and religion, maybe people would be less likely to want to move here.
The country is no more doomed now, due to immigration, than when 50,000 French Huguenots moved here in the 17th Century, 90,000 Jewish Refugess moved here prior to WW2, and the 6,000,000 of Irish Descent.
There are more Catholics than Muslims (including myself) and no one is up in arms about us, and beliefs are very similar to Islam.
