Parents whio question vaccines will only listen to honest scientific evidence, not tomfoolfery emotional blackmail guilt trips, they do not work on us.
i reject your ethics of emotional blackmail and think parents who question vaccinations are educated while those that jab away without question are foolish and ignorant.
