The left's most cherished right is that of abortion. It's the one thing they challenge any judicial appointee with. Will they uphold the right of abortion? The justification is it's my body and my choice. Attached to that is the idea that abortion is a medical procedure and like all medical procedures it's a matter between the doctor and patient and nobody else's business. It's a private medical matter and people who have abortions should not be discriminated against for doing so.
Is this not the same argument anti-vaxxers should be using today to refuse the shot? Why is their body, their choice protected but my body my choice not protected regarding my medical procedure?
If they want to argue that my choice affects their health, there's plenty of data to refute that claim. In fact, the opposite has been proven true, the vaxxed are a danger to the un-vaxxed, not the other way around.
All medical procedures should be a matter of choice. In the case of abortion however, the caveat lies in who's choice? If the state doesn't recognize a fetus with a beating heart as a person then there is only one person making the choice. However a valid argument can be made that a fetus with beating heart is indeed a person, one incapable of making any decision so the state has a duty to insure that person's right is also considered. Much like a severely disabled person who can't speak for themself must have a guardian who can speak for them.
So in that case, abortion cannot be so easily administered if it can be proven that a fetus with a beating heart is indeed a person with God given rights.
If you're somebody who's capable of using abstract thought, or self aware enough to see you've been unreasonable, you're no longer "on the left."
You can't reason somebody out of something they were never reasoned in to. Communism requires unthinking, low-vibrational, terrified drones.
