There are many regulation based on a persons weight, and just as many of those are illogical in some cases as laws/regulations/policies are which ban vaping outright.
Not all obesity is caused by over eating, eating poorly, etc. yet all obese people get the same treatment from such restrictions.
Regulation by government is seldom the one true solution(tm), it has always been, and will continue to be based on who has the money and time to have their case presented to legislators in a way that gives them "authority" to pass a law.
This includes outright bans on tobacco, a business should be able to determine for themselves if they want smoking inside their business or not, and it should be plainly posted so that people who have legitimate medical or personal preferences against smoking can avoid places where it is allowed.
Mate I agree with all that. My point was a comparison between smoking deemed evil to us and a deadly killer that must be eradicated to save our civilization from annihilation and obesity. Obesity is a killer much like smoking. Yet Obesity seems to be a hush-hush no no to talk about because we may hurt someone's feeling by calling them fat. It is treated more as a disability.
So here we have 2 "killers" smoking and obesity, yet one is demonized while the other is a "sssssshhhh" lets not talk about because fatty may have their feelings hurt. Next on the political agenda.... fining restaurants for feeding too much food to their patrons.
