The biggest reason is disinformation coming from social media and conservative media outlets. That can't be fixed while respecting the first amendment.
So? Get conservative doctors to endorse it. Or show outcomes and make sure risks are mitigated/taken care of.
That approach is being tried with some positive results, but it doesn't alter the fact that there is a tide of disinformation being pumped out day after day, a phenomenon few seem willing to engage with.
