I'm liberal, and I'm saying banning firearms in public is more of a "feel good" measure than it is actually useful. Unless you give pat downs as people leave their house then tons of people will violate this ordinance.

Your second paragraph pretty well contradicts your first paragraph as far as vaccinations go

Failing to be vaccinated does not cause direct, immediate harm to other people. It's a potential harm that isn't necessarily realized in any given instance.

And your third doesn’t follow any kind of logical reasoning since one of the ideas behind legal abortion is bodily autonomy.

Conservatives argue that a blastocyst is a human, since life starts at conception. Therefore, the conservative argument is that any abortion (aside from spontaneous abortions, AKA miscarriages) is intentionally causing the death of a human. Don't pretend like you didn't know this, since that's been their entire claim while working the legal angles to overturn Planned Parenthood v Casey (which is what actually overturned Roe v. Wade, not the latest Dobbs decision).

And most (not all) people who care to actually learn about gambling, or street racing, or cooking meth oppose regulating their interest. This is a meaningless universal truth about most hobbies, made even less relevant because a politician isn't picking a person at random from their supporters to help them figure out a subject, they're going to the "not all" people who care to learn and are willing to help.

This is the same argument cryptobros trot out whenever crypto legislation is brought up. These aren't complex subjects only a long term user could possibly understand. A gun is a relatively simple tool and a legislative aid could garner more than enough expertise in a couple weeks to understand anything necessary for regulation. The real reason this argument is made isn't because they want better and smarter regulation, it's because they want to argue that all regulation is illegitimate so they can keep playing with their toys unimpeded.
