For everyone in favor of a ban, realize this. You are granting authority to government to ban an activity, which is legal.
Just because you agree with this ban, doesn't mean you'll agree with the next one. By granting the government authority here, you're creating a hell of a fight for yourself in the future when the government creates a ban you disagree with.
As long as you understand that and are ok with it, then I guess that's your perogative.
Yep, this is what I have a problem with. We stop choosing and thinking for ourselves and let the government decide what we can and can't do because of health reasons. The pressure is already being put on the fast food restaurants to serve healthier meals. If it is ok to ban smoking this year then in a few more years we might see a ban on things like hot wings or cheese burgers.
