We should advocate for regulations that help reduce unwanted pregnancies and reduce the situations where people feel like they cannot afford them. That naturally reduces abortions.
Many people who are pro-choice (myself included) don't necessarily support people aborting for no reason but think that should be left between a woman and her doctor to work out.
I don't think we should regulate things that get in the way of religion because we are a minority. It doesn't end well if you pick a religion to regulate. I will consult my own Rabbi should I have a question on abortion. I can only do that if they are legal.
I quite frankly find your watered-down Judaism nauseating. You call yourself pro-choice. That means something. Pro-choice means
advocating for legalized abortion. Then you pivot to not wanting to actively regulate abortion, which means you aren't really pro-choice. You don't want religion involved because we are a minority (an absurd idea) but of-course we really should advocate to minimize unwanted pregnancies.
Sorry, but Judaism isn't based on wishy-washy, half-baked ideas. Frum Jews always abhorred pro-choice which means advocating for freedom to murder at the flip of a dime. Healthy frum Jews also don't have an inferiority complex so they don't view the fact that they are a minority as a reason not to advocate for their rights.
