Ask if they close their window blinds at night

You got curtains? Interesting, why? Got something to hide?

If they've nothing to hide, then why are they so dodgy when things like lolicon are discussed? Their actions speak louder than their words ever could.

There is an age old practice from olden days of the internet. If you don't want your nudes out there, if you don't want your name out there, if you don't want anything of you out there - you don't put it out there. Because once it's out there, you won't ever know who'll see it much less, have it. I always assume, that as soon as I upload a picture of myself somewhere on social media, someone would've had to have right clicked and saved it already. For what purpose? Who knows, could be a matter of some sick personal collector of people they particularly are fascinated with to potential murderers who're only lacking my location but should they find me out in the open, they'll know what I look like and probably kill me. And anything in between.

But so many people on Facebook, complain about how it is that they make new accounts and suddenly are presented with familiar faces to re-add as friends. Whether or not it's a new e-mail to even a new location, Facebook knows you so well by now, that they'll pitch you all of whom you've had, even if you don't want them. That defeats the point of wanting a refreshing restart on your life when all you've got is reminders.

Black markets also exist that circulate your data. Why would one think that one day, they're seeing a bunch of transactions that they didn't authorize all of a sudden? Well, somewhere at somepoint, someone did seize your credit card or bank info and now is running hogwild on it.

They're not worried yet because it hasn't happened to them, but boy do the tables turn once people are affected by these experiences.

I would answer that like any normal person I have plenty of stuff to hide which I don't consider any legitimate concern of others, and rightfully so.

And that if that person has no dignity, they may bend over as much as they want, but they are also spitting in others' dish by making that bending over acceptable and common.

It's less that people have nothing to hide and more that you're not really sacrificing any privacy

Say "don't change the subject."

There is no countering that argument. It points to an absolute failing of empathy. Rah, rah Godwin's law incoming. If you can't understand "First they came for..." and realize that it doesn't just stop or start at ethnicity and instead applies to literally everything and anything you care about them it's gonna take a serious remediative effort to correct that worldview.

Like tomatoes too much? Straight to jail.
