Sweden is portrayed as beacon of human rights, let's use them as an example.

The rules now are tougher than US rules for citizenship. Sweden (like e.g., Norway) has a 8 year wait vs US's 5 year wait.
Sweden has minimum income requirements, none in the US.
Sweden is a white hegemony, the US is not and has never been. It's not a fair comparison when the US has literally always been composed of immigrants.
If you want a white hegemony, move to goddamn Sweden and leave us alone. That's not the US and to suggest otherwise is anti-American and ahistorical. If you clearly hate what this country stands for, then please do yourself and everyone else a favor and leave. Jesus Christ.
That is for a different scenario. It means that if you already have a residence permit, you have to wait 8 years before you can apply for citizenship. OP is talking about marriage green card. For 75% of cases in Sweden it is less than 15 months to get a residence permit.
