I think a lot of it is about control, too. I follow politics pretty closely and there are some people who just feel it is their duty or role in life to decide how the rest of us should live. Sometimes, they make laws and regulations with the best intentions or to please a certain special interest group at the time, but they don't look ahead to the consequences their actions can have on others or in the future. The law or regulation sounds good and noble to them, but the ramifications turn out to be disastrous in many situations, sometimes even causing loss of life. Of course, they generally only take credit for the successes and sweep the eventual problems under the rug or pin them on someone else. And many times, even when they get what they wanted passed, they still are miserable and search for another "control fix" and another issue to complain about, usually involving something based on flawed data that doesn't impact their lives in any way, but they feel the need to control regardless.
I know that even on here, some of the members who are yelling, "How can they think about banning vaping?" also post in threads supporting taking away a right unrelated to vaping that other Americans enjoy or feel is important to keep. If we say, "I don't care if the gov limits soda size or trans fat or hunting or gun ownership or baby formula or sodium because none of those things affect me," then we shouldn't be surprised when they have an easier time regulating something that does affect us. Every right that we let them nibble away at "for the common good" makes it just a little easier for them to take big gobbles of the rights we care strongly about.
Sorry if I sound jaded. I used to be pretty optimistic about the power of the American people, but the last decade or so has beaten that out of me.
