What’s so wrong with keeping people safe? 

A sizable portion of the population thinks their personal liberties are more important than other people’s safety, and that’s not right. They don’t care if someone could pass away from breathing in peanuts on an airplane: they think their right to eat peanuts wherever they please is more important than an allergic person’s right to safety, and if someone believes that, there is very little you can do to change their mind.
