You've already been told that the death rate for 2020 reduced in line with normal levels because we more or less locked ourselves in our houses for the year.
Too much of your post is just baseless ranting to be honest. I don't think you've provided a single source for anything, for example.
In the meantime, variants absolutely exist -
here is an article on the BBC website discussing them.
Vaccines can offer different levels of protection against different variants. Delta is the most discussed one here, as it was the variant that arrived after vaccine trials had begun, and
here's the BBC saying "But neither [AstraZeneza or Pfizer] is as effective [against Delta] as it is against the Alpha variant, responsible for most UK infections last winter." In general terms, we can see how diseases evolve by looking at drug-resistant strains of various diseases, which are on the increase (see Bill Bryson's
The Body for an excellent discussion on that)
Sweden did have excess mortality last year -
7.7% per Reuters, highest of all the Nordic countries. Probably their culture played a part in avoiding the worst of what hit Italy/Spain - the Mediterranean cultures will see a lot of kissing when you meet (which is great for spreading the virus) whereas the Nordics are more restrained. In that regard, it's not a good sign that Sweden's excess death toll was significantly higher than the other Nordic countries. It also
has the lowest rate of smoking in Europe and when there's a disease that hits your lungs, being a smoker is not a good thing. There's probably other factors too; I'm not an expert. But still, there's way more information in my argument than there is in yours.
I'm also not sure why you think you can ignore the Italian experience just by shouting "But Sweden!" and offering no sort of insight or information or anything. Even the Irish experience over Christmas - when ICU filled up within a couple of weeks of people enjoying Christmas - should indicate that this is a real thing, and that being vaccinated against it and staying out of hospital is a positive thing for society which trumps your own personal bull**** of "My body my choice"
