Don't know what that's supposed to mean. Someone supposedly racist said something similar, therefore anything who says something even remotely similar is now a racist by association? There's a fallacy here somewhere...

The BNP used to be popular party among open racists in the UK, and they used similar rhetoric to convert people to their ideology. Hence the reference. The sentence I quoted is textbook European racist rhetoric, from concern about British people & culture (implying that only white Brits are British), to calling immigrant communities "international villages" (implying that immigrants don't have a right to be in the UK & implied classism/elitism).

That, combined the fact that you are appear regular poster to a white supremacy/neo-nazi subreddit is why I'm pretty confident in calling you a racist.

There where did the slogan "Diversity is strength" come from?

IDK not me. This my first time hearing it.

Talk to me when they start forming a rainbow coalition against the native Pakistanis to advance their own interests and import more of their people.

This doesn't make any sense to me. Why would they do that? What's a "native Pakistani" anyway?

The context of America and it being created after pushing out all the natives is irrelevant here.

It's exactly relevant. The supposedly more culturally homogenous nation that he was defending relied on the genocide of the black & native inhabitants of the land. If he actually gave a shit about the negative consequences for people he would have acknowledged that, but he was only concerned about selfishly protecting his personal interests. The "national spirit" he's talking about is preserving the country in the way which genocidal colonists intended it to be.
