Brexit

[NorthernRaider]

Soooooo having millions of Brits move to places like India, Somalia ,Kenya, South Africa etc in the 1800s and overwhelm the local cultures and practices it is Colonialism, Racist, Oppressive and Imperialist, but when millions of Indians, Somalis, Kenyans, South Africans etc move to the UK its diversity, multi culturalism and diversity and is good !!!! So how does that work then?
I also note that in the media today that apparently it is racist and xenophobic for white British people to want to protect their heritage and cultural roots and identity, But when its Black or Asian people retaining their dress, culture, habits, customs etc they are seen as celebrating their cultural identity........ even if it displaces the indigenous culture?
