The protesters are people, and I agree with those people as far as against another lockdown
The problem here is an undercomplex idea of "freedom" or "liberty" that has plagued the US for years and that a far-right movement longing for a new idea to cling to except for "weren't Hitler and Mussolini great" is trying to import Europe, which will hopefully not be fruitful.
Personal liberty ends where one's actions negatively affect other people's ability to excercise their freedoms. This is agreed upon within anarchist, liberatarian, (neo-)conservatives and classical liberal thinkers.
The problem with covid lockdowns is that they are proof of bad statecraft. We can see that you can steer througn the pandemic with more granular measures than lockdowns, but also without killing an excess amount of people (see: the Nordics, Canada) if you react early enough. From this point of view I can understand why people protest.
But that is not why
those people protest. They protest because they believe that governments are taking their liberties away out of spite, in the name of "healthcare dictatorship", "government overreach", or even "international judaism." Most, if not all of them, are also vaccine refusers and deny covid exists/is as bad as, well, it is.
And here the undercomplex concept of liberty comes in: Unvaxxed people who get covid block hospital beds. If they die, they may well die, I hope they do, by now. But it's not only them that die. It's old people having a heart attack who can't get an ambulance because they are all out for covidiots. It's motorcyclists who had a bad accident and can't go into surgery because there's no ICU bed to keep them alive afterwards. It's young women with complications during childbirth.
So, as a society, we can chose between "mandatory vaccination", "covid control measures that in cases of bad statecraft include lockdowns", or "let innocent people die in the name of other people's freedom." The latter of the three options is the US model on school shootings, but it is, again, based on a stupidified, egosistic, deeply anti-social concept of freedom that is hard to defend, even within a Thatcherist "there is no society" framework.
