In my grandma's village everyone knew that a neighbor was cheating, who got pregnant, and details about every single person in the village. Nowadays it's easy to track which websites I go to, but none of my neighbors have any clue about what I'm up to.
With this in mind, outright calling people that notice this gaslighters is immature. Make your point or don't.
You've literally just pointed out the difference between the people who used to know what you're up to, and the people who now know what you're up to.
Anyone trying to convince you there is no difference between the two states is trying to make you ignore that difference in the world, and convince you that your perception of that difference is faulty or mistaken.
How is that not gaslighting?
But - the difference in effect is that, under the old system, the government could not immediately get a summary of that information from everyone in the village, and do so without possibility of word getting back to you. Nor could a prospective employer. Or a bank manager. Or someone half-way round the world wanting to scam you out of your life savings. Or someone wanting to run for political office. Or someone wanting to persecute cheaters/unwed mothers/"sexual deviants"/etc... for personal gain.
Yeah, back then your private life might not have been private, strictly speaking. But at least it wasn't for sale, in bulk, at bargain basement prices, to anyone looking for any kind of leverage over you.
