Just on this point here.If someone is opposed to vaccinations or a lockdown, that should be their democratic right as part of a free society
You are right it is their right. However most of the people on the internet with this view aren't just stating an opinion. At least here in the states threats are being made and in some cases carried out. Some lunatic said she would go to a school board meeting with a loaded gun if they imposed a mask mandate. That is not an opinion. That is a very real threat.
Parent's going to schools, fighting with staff and teachers. I'd dare argue their children are better behaved at least until they actually see what their folks are doing. Why this stuff is so polarizing I don't know but around here it can get you shot or knifed in the back. Even these days when businesses are within their rights to require people to wear masks and such I see someone getting thrown out of a store or other location regularly for violence against employees and such. They are not expressing an opinion. That is become a danger to society. Big difference.
