racism is where someone says they are all like this or that, which I have never done

That's precisely what you are doing - you're saying that 'they' are not like us, so that our country and our culture won't be enriched by them but must be protected from them. To quote from your earlier comment, "the law, the land, the people, the culture should be linked". Our land, our culture, our people, our law - it's not theirs and it's not for them.

If that isn't racism, I don't know what is.
