Private citizens should have a right to private conversations with one another, regardless of the channel. Why is this so hard to grasp?
Some people are fundamentally willing to sacrifice rights they don't view as necessary for some temporary gain, and trying to oppose this in any more direct way can result in having one's own moral standing challenged.
I think you meant to say "sacrifice everyone's rights." This isn't an opt in scenario, it would be your right to privacy being forcibly taken away.
