“But your blind allegiance to vaccinations are duly noted.”
I hope your kids don’t end up blind or dead because you refuse to acknowledge the profound and unarguable truth in the effectiveness of vaccinations.
Do what you will with your own kids (though I do feel sorry for them) but don’t hurt other peoples kids by pretending to somehow know more than those who literally save millions of lives through vaccines and mass immunization efforts.
