"I would be amazed if some of those attending these anti-lockdown protests would be alongside the likes of right wing types..."
If these are anything like the US protests, which I think they are, then far right / alt right organisations are very much involved. In fact, some are heavily funded by such organisations and are not grass roots movements at all. It's astroturfing. And there is a coincidental alignment with anti-vaxx types and conspiracy nuts and certain libertarians which is useful to them.
