Anti-Vaxxer marches solution, page-27

True that Covid can be transmitted by those who are vaccinated but
with much less probability than those unvaccinated and in prticuluar
with the Delta Strain.

Those who are vaccinated are taking reasonable precautions for
minimising transmission while those who are not vaccinated are not.

The lack of precautionary actions which led to AIDS transmitters
passing on the virus was the key legal argument leading to their conviction.

In law, it is a reasonable defence to say that one took all presonable
precautions to prevent the damage. IMO Anti-vaxxers who demonstrate
massless in public can't say that they took all reasonable precautions
to minimise Covid transmission.

That said, those (like the Trump Congress invaders) who don't have
money or assets are not suable; just liable for criminal punishment.
