I don't think people worry about them, as much as they need to talk about them, because so many people have had some sort of an experience that they can't explain. It's part of our collective consciousness. And it's perfectly normal for people to want to talk if they have seen something in the sky or had some closer encounter.

What isn't normal is all the government suppression of anyone trying to report it. Even when whole entire towns and cities see something in the sky, it will be followed up by a joke and then the whole story will be buried. And anyone who freely talks about their contact with aliens, even if they are well-respected government employees get discredited and made to look insane.

Pilots, Astronauts, have frequently and continually reported for and have film footage to show with it. Just last week there was a story release with video and audio of airforce pilots spotting ufos. Also navy ships out at sea have reported ufos and usos (unidentified submerged objects).

And then there is everybody else. There is no typical type of person who has had an encounter.
