Personally, I use the argument that it's not about what's illegal or unacceptable now, it's about the future. In the 1920's, nobody thought hanging out with a couple of communists in college one time would come back to bite them. It's unreasonable to think that it would. But it did. So it's not that what you're doing is wrong, or that you have something to hide. It's that someday, something you do today could come back on you. Better it be something that you choose to share than something the government discovers and keeps records of.
