The only way to make people who are not us, not resent us, is by physical separation. This is a hate fact, I know, and I am sorry.
Except perhaps certain groups who have a track record of performing well in our system. Actually, some groups perform too well, and that can result in resentment also. For example, I have resentment for the fact that so many Jews have gotten away with genocidal, anti-white speech and suffered utterly no consequences in our society for so long. Example: Harvard's Noel Ignatiev (recently croaked, rest in hell).
The only solution is walled states / provinces and carving out territory to separate - perhaps leaving those areas which desire to remain mixed. They're coming for you, white man. Get with the program. How many more videos do you need to see of white statues being toppled or white men / women / children / pets being mutilated or beaten?
It’s obvious that we aren’t all getting along. We don’t trust each-other enough. Multiculturalism is doomed to fail unless there is a persistent, dominant over-culture that everyone must conform to. The solution is freedom - allow those who want to self-segregate to do so. This could be accomplished by a large program designed to organize and financially incentivize property exchanges between two source-territories.
I never noticed the parallel between conflicts between different nations in the past, and conflicts within a multicultural society, but now that you point it out - you're right, multiculturalism is a country-scale reproduction of what the world used to be, and it's facing the same problems.
My deep appreciation for the values of the European Enlightenment are the reason I'm here and made me turn against the left years ago. They are great values, and I'm not ashamed to admit I look down on cultures and people who hold opposite values (like the oppression of women in certain parts of the world, to name one example).
As for what can be done about it... I think there's still hope to reverse course. People need to speak up against all of this, although in Canada I realize many people are afraid to do so. Unfortunately, this silence is what lets the radical left push the envelope further and further.
I hope that places like Omega Canada will be a start to help Canadians realize they aren't alone in their opinions, and will encourage them to share these opinions with one another. I realize not many people would join this forum, but with smart, targeted activism we could win this and encourage more discussion and opposition to radical leftism in Canadian society.
