What about that time you posted a meme to your friends discord server making fun of Donald Trump?
This is a good example because they can and have started going after this type of stuff. I think it's still going to be failing for some time, but that they even try, that people even get arrested is terrifying.
The best way I can explain it to people is that you think you have nothing to hide now but you think that because you agree with the government. Maybe a good way to explain it to conservative folks would be to say something like "what if they imprisoned you for sharing your religious beliefs?"
