I have relatives that think the way the person you're replying to does. "There's no way it can be safe."

I was grieving their position last night (momentarily, I've accepted that they think this way but it still makes me sad). There's nothing I can do to persuade them. The fact that I've had four jabs and I'm still fine isn't worth pointing out.

I agree with a sibling comment that says it isn't worth trying to educate the willfully ignorant. However, you did a great job of saying it concisely. I appreciate you.

Ask me if my relatives have american flag iconography on their walls. Spoiler: they do. It's almost as though there's a very specific type of person who falls for this shit.
