If you're not worried why is she "dangerous"?
I usually wouldn't keep responding to an anti-vaxer, but I don't want that statement to be the final one, so screw it.
She's dangerous because she's spreading anti-science bullshit. People like her are the reasons fucking measles/mumps/etc are rapidly returning to harm children because of moronic parents who have stopped getting their kids vaccinated.
Also, just on a COIVD-19 specific level, there are a lot of people for whom vaccines aren't enough or aren't workable, specifically people with compromised immune systems like the elderly or people with/being treated for cancer or autoimmune disorders. They get the chance of being exposed to COVID more for every asshole who doesn't get vaccinated when they can't. Then there are just the elderly or ill who can get vaccinated but who are still at a higher risk if they get it even with the vaccine.
I'm sick and tired of selfish morons ignoring science because some dumb asshole told them that vaccines are bad and drinking bleach or injecting dangerous horse medication is the way to go. This goes for COVID, general vaccines, whatever. Imagine if idiots like Lily had existed in this number when my Grandma was a kid, we'd still have fucking polio ravaging the nation.
Thats all I'm saying on the subject, I have better things to do with my time then try to argue logic/science against anti-vax stupidity, like slamming my head into a brick wall or beating a dead horse.
