Wow. No. Just no. This comment is so wrong, to remotely compare any of these things to smoking and drinking. And even if we stipulate (even if, since the science is poor) that these are contributing factors, nobody thinks they increase risk enough to make a dent in the statistics we're talking about here.

I think nobody may be a bit of an exaggeration, e.g.

"The risks of a high-protein diet are even comparable to smoking, the researchers said."[1]

The study that article is based on (well, there are several layers of 'articles' between the SA article and the actual study) is particularly bad (in a field where bad research is pretty much the norm)...

High protein or high in red meat? There's a huge difference there. If I eat a high protein diet with my protein coming from e.g. soy, am I still under the same risk?
