I just have to keep reminding myself that you're not full grown yet. Think about this.. 40 years ago doctors were encouraging pregnant woman and fat people to smoke to keep their weight under control. No one back then could have possibly conceived that one day they'd have people suggesting that criminal charges be brought against them for smoking around their own children. Grown ups know the implications of the EPA classifying human exhalations as toxins. Wait for the first lawsuit because an employer is making someone work in the same room with another person. When you think it can happen, remember that no one would have imagined smoking restrictions like we have now 30 years ago.
And forty years ago, race relations were at a boiling point. 40 years is a large difference, much growth.
While once again, someone is bringing my age into this, do realize I am not ignorant of the past. Do recall, it is my generation that is trying to avoid the mistakes that previous generations made, including yours maybe. (Don't know your age.)
Grown ups such as myself also know the definition of something called frivolous lawsuits. You are acting irrational with your thinking, using what if thinking and apple/oranges examples to try and prove your point.
