Increase in obesity like most other addictions is directly linked to people being shitty and treating each other shitty.

If no one finds a reason worth losing weight for then no one will even try to. If eating is your escape mechanism then it often is worth being unhealthy in order to rid of a portion of daily pain.

Remember that a majority of people will not find acceptance whether or not they are healthy, thin or generally striving to better themselves. No one gives a shit about these people before they develop an unhealthy addiction but somehow there is an abundance of morons who cry and whine about their negative effect on others. Why should they care about what you have to say now?
