absolutely non-harmful. I always love that blatantly disagreeing with empirical scientific evidence by ignoring strongly studied facts is considered a matter of "opinion". It's like saying, "in my opinion the World is flat". "In my opinion artificial sweeteners are harmful and cause cancer", or, "in my opinion, vaccines cause autism". When did we become so narcissistic to think that just cause it is our opinion the World should "respect" whatever stupidity we are gullible enough to believe?
