The mantra that our liberties have been going away gradually is often repeated but not at all, or in any way, true.
If you want to talk about domestic spying, how about:
Plus, I guess you are only talking about white people, because the liberties of every other kind of people are very obviously less eroded than they were in the recent past. I think things like being allowed to marry a white person, or being allowed to buy a house is a pretty important liberty that some groups were denied, by the government, and now the government doesn't deny them those liberties. So that's a pretty big win for liberty.
Blah blah blah, right do not come from governments, blah blah blah. The government can't 'create' rights, I guess, but it sure as hell is the only thing between you and the army of goons that would swoop in and deprive you of your life and property. I'm sure you think that you don't need the government to protect you, right? I mean you could just join together with your neighbors and protect yourselves without the government. But guess what? The 'government' is just all of us joining together to protect ourselves, that's literally all it is. So you can whine about the faceless 'them' coming along and stealing all 'yer liberty', but it's just a bunch talk-show-talking-point agitation propoganda bullshit that has been spoon fed to you and you are just puking back out onto the world without bothering to think about it critically.
Humans long ago decided it was better to band together, because the alternative is to get robbed, murdered, or exploited by whatever gangsters happen to show up and defeat us in detail. We've developed fairly sophisticated ways of getting the good parts of government (protection, contracts, regulated externalized costs) without the bad parts (explicit oligarchy, autocracy, large scale warfare for the personal enrichment of leaders).
