I'm a little skeptical about the claim that unvaccinated are causing mutations. I remember there being hysteria a few years ago about overuse of antibiotics and that causing mutation of bacteria, not people NOT taking antibiotics. Same with bug poison, overuse leads to immunity.
Though I'm going to be absolutely honest, I"m a graphic artist by profession and musician as a hobby so I'm hardly a virologist.
...another hobby is being a ahole on political threads.
I think it is pretty much a known thing that a virus, any virus, can only mutate when it is growing and living in a host and transferred to a new host - - if there are no hosts there is no place for the mutation to take place. without people to infect a virus dies off and without people it can't mutate - - so if only or mostly the unvaccinated get the virus then that's where it can mutate
