I think it means take some action to oppose it legally, say be contacting someone, writing. Whatever you can lawfully do to register that you will not accept it any more.

Sadly, I thought more would have rejected the vax out of the gate but that ship has sailed, so the least we can do is see that it was pointless (it doesnt even work) and protect the children from what is a greater risk (taking it) than them not having it. Same for masks, anyone reading this that still wears them is a COWARD or an ignorant bastard, no excuses, they do not work.
