This is what normally happens with most viruses

Yeah, not this quick and not for that reason. The virus doesn't become weaker, people become more resilient to it. A woman gets a virus, lives, passes the antibodies on to her kids. Kids have natural immunity to it without ever encountering the virus. That's over human generations.

In a single mutation, covid became less deadly than the covid vax. That means evolutionally pressures forced it to drop likely what was artificially added. Hence evidence of gainofunction

See, we have a lot more in common than you think, man. We're all on the same team here even if you don't want us to be.
