ELI5: Why is it acceptable to shame smokers but fat shaming gets you in a lot of trouble, when lead to health problems?

It's not really acceptable to shame anyone for anything that they choose to do.  The problem with fat shaming is that being fat tends to be a self esteem issue and further breaking down that self esteem by adding shame just makes the problem worse.

Smokers smoke for many reasons, but rarely is it because of poor self image.  It's much more likely to be related to stress and addiction to something you started as a child.  So adding shame does not necessarily make the problem worse.

However, it's still bad to shame people for making legal choices that don't harm others.
