E2E is not enough. You can still be subpoenaed for Signal messages if they aren't auto-deleted. Just ask all the folks involved in the trump indictments.
Because people need to think of abortions access as health care. The same as cancer treatment, diagnosing illness, or getting stitches. And that starts with messaging.
First off, when you say "isn't abortion" it kinda sounds like you're talking about mythical post-birth murder, which doesn't happen and would be illegal. Not sure if you're talking about that or not, but I thought I'd preface.
Aside from that, when it's "viable" it's usually just induced labor. If it's not induced, there's a reason why they have to take more extreme measures.
Aside from that, if you give an inch they take a mile. I would rather doctors and their patient be able to do what's best for the patient's health than to let the government interfere.
