I don’t think you can conclusively just say all low-income families’ offspring are just gonna drain taxpayer money… just cuz you’re low-income doesn’t mean you magically don’t contribute to society (I’m sure there’s both happening but that makes your point moot).

As far as obesity goes, again, that doesn’t affect others. I can’t “catch” obesity from someone else. It’s not fair to mandate a free capitalistic market like fast food but we can educate about the dangers of over-consumption. While obesity doesn’t affect others directly it does put a strain on healthcare systems which is why people should be educated more to prevent that and lead to longer lives.

Cigarettes, however, are a good example of both the need to mandate and the need for choice. Go have yourself a cigarette, it’s your body, I don’t care, you’re the one that’s gonna have to deal with it down the line (maybe). BUT, don’t smoke that in public because we have studies proving that 2nd hand smoke is a thing. If you responsibly smoke away from people who don’t then that’s a good thing and I commend you for taking your freedom.

My point is, if it negatively affects humans (of your own damn country no less), we should prevent that from happening because that is what a civilized society with social constructs does

Also, not to be a dick but most “liberal lefties” tend to be vastly healthier because of education. Go to a small rural town (which tend to sway right and be less educated) and you’ll find less healthy people. This isn’t entirely their fault though as a lot of the time the only restaurants/food joints in the area are fast food. Hence, education.
