You are right, husband is dumb.
Hell, the only vaccine that has the demonized ingredient (That never caused autism) is the flu vaccine.
Never bow to Q-orons.
Also, Q-orons are not kind hearted, they want to watch the world burn. Because reality doesn’t curve to their bias.
They are crazy.
They’re buying into a repackaged antichrist scenario.
You can’t get people like that to change their minds. Anti-Vaxxers will never change their minds no matter who they talk to. I’d keep my kids safe.
They don’t have kids yet. Even if they’re trying, it might be years until they do. If they get pregnant, you could revisit the issue, maybe have a talk with your doctor and your husband.
It’s not an issue right now, and it will only become one if they have kids before yours finish their vaccines. I myself would drop the subject, honestly.
