Most Canadians would love the idea of states joining us
Nope. Not true.
They wouldn't even refuse solidly red states, I think
I would. They would view us as an occupying power, and would be right to think so. Think of Quebec, but instead of being French they're just racist. I don't want that in my Canada.
It would make Canada stronger, and a better life for the states
It would be a clusterfuck. Not Canada's problem to make life better for Americans. Ever heard the saying, people get the government they deserve? Majority of them are assholes or unable to help themselves. If they want to enjoy a better life the Canadian way, they can work on immigrating here. Canada is not an expansionist country. Plenty Happy as is, geopolitically speaking.
Economic power together is enhanced
We've been doing this already, as two separate sovereign nations. Assholes turned it against us. You know, you read the news.
Canada even as 10 states instead of 1, doesn't work because US debt is too high, and US simply has too harsh of a society meant for oligarchy.
Not sure what you're going on about with the US debt. But that alone is a reason for us to not join together. Who the hell would want to inherent that problem? Canadians would be taxed like crazy to help pay that off. If by too harsh of a society, you mean ruthless individualism at the expense of the overall social fabric, which has a nasty effect of creating oligarchs? Correct.
Healthcare would be a major issue.
It would be, but in this scenario is would ironically be the least problematic thing.
These opinions are presented to you by a dual citizen Canadian currently living in the Southeast of America. No normal people here want to invade Canada, and no Canadian wants to be a "savior" of poor abused American states. I'm down to let more people immigrate and become PR or citizens, but not a blanket annexation of entire states. If Americans have a issue with their current federal government, they can take some bricks and throw them through select politicians windows while doing mass strikes like the rest of the civilized world does to keep their democracy clean. The French revolution wasn't bloodless, nor was the American Revolutionary War. Tyrants don't go away on their own.
You know nothing about Canadians nor what the average American thinks and it shows.
You're 10-ply bud. The only person showing a gross lack of humility here is you. I'd go into depth on why what you said is stupid and is bad history, but smart words are wasted on deaf ears. I can tell you all the historical facts backed by primary sources all day, but I can't teach critical thinking. That lack is critical thinking is what got you here. But hey, go ahead and keep on using bigger words to shield against that fragile, threatened, intellect of yours. I'm sure it will make us agree with you more instead of actually citing sources or doing any attempt to explain why you think what you said made any sense. So far you argument is "Field Marshal Zhukov said otherwise once" and your source is "trust me", and hiding behind the opinions of unnamed peoples who are more accredited than me (therefore default right-er-er than me!!), along with copious, pitiful, abrasive ad hominen attacks (I know big words too!!).
Real talk. I don't know what you do for a living, but I recommend you stay in your lane and I'll stay in mine. The electrician shouldn't tell a plumber how to bend pipes. Whatever brainrot is making you sanctify a long dead Field Marshal of the USSR, one responsible for the extremely brutality on the civilians of East Germany and especially Berlin, you should do some serious introspection as to why. You glorifying this man shows you are severely detached from reality, let alone equipped to debate history.
Oh, and I'm under no pretense to be polite or humble when talking about history here. This isn't a history conference, its an anonymous forum. I can be as crass or rude as I want here. Frankly, I should've just told you to pound sand instead of writing all this out. Do me a favour, and trust me when I say that what you said and think is stupid as hell. Your homework is to use the boundless expanse of the educational internet to figure out why. I say this with sass yet genuine concern; educate yourself better. Your mind deserves better.
