Every group that isn't us hates us. From my years of traveling, I can promise you that. They want to take over, take revenge, humiliate you, and subjugate you. They hate your country, values, religion etc. It's one of the few things I'm certain on in this life. If you don't see this reality, you will pay for it with your bloodline in the near future.

Most people don't hate us. They don't care.

The people that are here however, are different.

My only hope is for a major economic disaster that'll, through accelerationism, will allow for dramatic instability, allowing the British military, majority white, to preform a brutal coup and end the British parliament and force mass deportations

The economic collapse will cause enough self-deportation that you don't need a coup, and you still won't need one if you have reasonable political actors. Speaking of the US...

America is already subverted at the governmental level, although this process is slower due to constitutional rights to free speech and the right to guns.

Subverted by the right. The Left were already fully in charge at and institutional level and we've been recovering now for 2 months with good results. His analysis of the American situation is backwards.

I feel sorry for those stuck in England because they'll experience war in the next 20 years

Dead wrong. The Left aren't going to fight to keep England, they are too small and hate it as it is. Only the Right would be willing to fight a war, and they don't want one, so there won't be one.
