FlyerTalk is fundamentally a travel site. Travel sites are not in the business of giving (or even merely repeating) health warnings.
If you are booking a hotel room on Expedia or any of the countless other sites that conduct such business, and you want to request a smoking room, does the website first make you read a warning about the dangers of smoking? Of course not. It's not the proper role of a travel-related site.
Some travelers drink too much, especially when they are actually away from home. Some cheat on their spouses. Should FlyerTalk warn people about those bad behaviors, too? If not, why not? What's so special about smoking that FlyerTalk should single it out for health warnings?
