All of you- shut up. Lib has a legit point. Normally assimilation takes care of cultural homogeneity, but if the birth rate fall low enough you have a situation resembling the late roman empire when they invited germans into the empire because they needed someone to work the increasingly vacant fields. Population and cultural replacement has happened lots of times in history.
If this was a Native American lamenting how the whites were reproducing too quickly and thus they were going to overwhelm his people, would you give him this same response? No; he'd get all the sympathy in the world. So stop being hypocritical. Cultural annihilation is a legitimate fear (unless of course, you think everything made by dead white men must all be worthless, like democracy, anti-trust lawsuits, and the Romantic Era of music. Yes, it sucks that you had to be a member of the privileged race and sex to be able to make this stuff. It's changing, slowly but surely. So stop boohooing the past and go write a piano concerto if you're a woman).
An the other hand, um, we should be reproducing at that rate. The population needs to decline if we're not going to run out of freshwater and arable land. It's just poorer cultures have just been unbelievably dense to this idea (Look at Africa, where they keep having babies right up till they die of starvation).
Also, if you're a sovereign nation, you can do whatever the **** you want with your borders. So why not close them? Does the western world still want the cheap labor but not the actual people? In America at least, there's just too much public support in favor of immigrants to pull that off (myself included, hell I have family friends who are illegals).
So yes, our future may very well contain 'dark-skinned' people, don't care in the slightest about that, but what it won't contain is the 'Islamic republic of Great Britain', that's a story invented by Americans to convince themselves of their own social 'superiority' over the UK.
No, we can claim that because we don't have cameras on the streets watching our every move. Hard not shake the image of British docility when you read about that.
I mean, it's not as bad a canada, where a misogynistic gunmen entered a classroom and ordered all the men to leave the room, when it was obvious he was going to kill all the women, and they
just left, but you get the picture.
