Not all the points in your OP are true.
first 2 lockdowns, both brought down the rate significantly while on lockdown, enough to protect the hospitals.
Currently, we are heading to people not getting treated when sick with Covid due to hospitals being overwhelmed, and loads of people already dying etc of other things as there is no spare capacity in NHS. NHS staff on their knees and facing being overwhelmed.
suicide rate did not rise at all in lockdown, in fact, in went down at one point much to everyone's surprise.
religious freedoms? I go to church every Sunday on zoom. Not as good as in person, but it works. And technically we could still meet, but we have decided not to.
Nothing is stopping be from praying, reading my Bible, talking tomy friends about my faith, I have worked in countries with no religious freedom, this is nonsense to suggest we have lost it.
save lives v. people dying. Yes I agree that people are dying. They will either die of cancer or covd. Not a great choice, but if we don't lock down, then thousands and thousands more will die. It is awful to not get treatment for cancer. It will be worse (as in total numbers of people dying) if those people die of cancer plus thousands die of covid.
Civil liberties - interestingly dh and I were talking about this. Countries with very few civil liberties eg China, Taiwan etc have done very well in controlling the virus. The more freedom a population has, the worst they have done, so Japan and Korea, not so well, and then Europe and USA have messed it up. So I would suggest that the fact we normally enjoy a lot of freedom, is exactly why we are in the mess we are in. (not that I think we should have less liberty, just an observation)
I am in support of this lockdown. We should not have relaxed over Christmas, my area, which was doing OK in November is now seeing rocketing cases. My local hospital is overwhelmed, and we haven't seen the Christmas spike hit yet.
This wave is so much worse due to the new variant, without the new variant, we would ahve been Ok doing tier 3 type things
