Question: Are we being visited by aliens? Why don't they drop by and say hello?

Answer: "I sincerely hope there is intelligent life in space... because there doesn't seem to be much down here. That must be why we only ever get fleeting glimpses of UFOs. If you were visiting a world full of primitive, aggressive creatures, you'd want to stay safely in your car, too. You certainly wouldn't park, approach a local and say, 'Take me to your leader...' I mean.... just LOOK at our leaders!"

And look at the idiots who vote them into office and/or help them slip through the judicial system.
