You seem to have two basic arguments:
1. That the lock downs were unnecessary/ineffective.
And since the evidence and experts disagree with you, it seems incredibly dubious that you're right. As with climate change denial, there is always some minority taking the contrarian view, but the scientific consensus should still rule the day.
And even if it does turn out to be true, it was still the scientific consensus during an emergency, so it made sense to do it as the best available option. We can't undo the lock downs and we're already working to phase them out. So there's really no cogent argument here.
Also, the comparisons to the flu are a sign you don't have your facts straight. Expert models predicted the potential for millions of dead Americans without intervention. And it seems entirely backed up by the actual data we got from New York.
You also don't seem to understand that flattening the curve reduces death, it doesn't just spread it out over time.
2. That the lock downs are bad for freedom.
This is entirely based on the slippery slope argument. You can't actually point to any governmental abuse, at all. Every government official seems to be acting entirely in good faith across a massive country. Which is why no reasonable person is worried about this. The people protesting the lock downs are a tiny minority of extremists and contrarians.
You have to ask yourself "am I being too extreme in my views, or is every educated/informed person blind to the danger?" and it's pretty obvious which of these is the case.
There is simply no justified cause for concern that lock downs are going to become a tool of oppression. The lock downs are happening with the consent of the people and the courts.
And it's extremely time-limited, not open-ended. There is absolutely no way the lock downs will go on indefinitely. And there is no way they will happen again without the consent of the people. There is simply no reasonable cause for alarm.
P.S.
I would expect your position on allowing people to poison their fellow citizens with radioactive material might be similar to your position on poisoning people with a deadly virus. That would be consistent with the extremist views you're espousing.
