Would you use teleporter technology if it existed? Why or Why not?
You know those sci-fi teleporters like in Star Trek where you disappear from one location then instantaneously reappear in another location? Do you trust that they are safe to use?
Yeah, and there are people that refuse to fly because they're afraid of crashes, but still ride motorcycles without wearing helmets. A character refusing to use a transporter just indicates that the person in question isn't reacting rationally. Likewise, irregular malfunctions don't mean that it's not still safer than other means.
"How many Transporter accidents have there been in the last tens years, Reg? Two... three? What about the millions of people who transport every day without a problem" - Geordi - TNG Realm of Fear S6E2
