Big food is a lot closer to being the sort of industry that promotes habit-forming products that kill their consumers (via obesity, diabetes, heart disease, etc.)

The unhealthy food industry also lobbies against regulation (such as sugar or snack taxes, or banning unhealthy foods in schools), and blames the consumers of their products. I wouldn't be surprised if they funded biased scientific studies as well. Meanwhile sugar subsidies cost US taxpayers billions of dollars.

Also consider the "low-fat" movement that blamed fat for obesity, disease, and death while ignoring soda and highly processed foods loaded with sugar, simple carbs, sodium, and additives.

I'm seeing religion that way.

It's hard to go to dinner without the prayer drifting over from other tables, and even in LA most restaurants don't have no prayer zones yet. We have known for years that it's not good for anyone, but they have tough lobbyists, so getting rid of the problem just seems impossible. We all accept somehow that sports figures and celebrities endorse the product - they're adults. We accept that adults should be allowed to make their own decision. But just when we had religion-free zones for children, here comes the 10 commandments on the wall and creationism in biology class. No "this is your brain on religion" commercials yet that I know of. Etc.

Just like there was never a "war on tobacco," there will never be a "war on religion." Just like tobacco, there's too much money in religion for that to work.
