What is or is not of public interest changes depending on who you ask.
America used to be a country where people minded their own damn business.
Now everyone has some bullshit excuse to get into your business.
(whine) I have a right to make you stop smoking it effect my air. (Unlike the big SUV you are driving)
(Whine) It affects my insurance rates. (That is a problem you need to take up with your insurance companies and if they don't listen talk to your lawmakers and pass laws making the insurance companies change how they do business)
Your rights stop at your nose. You do not have the right to know someone else' personal business.
This is the same bullshit excuse people use for anytime they want to stick their nose into someone else' business.
The excuse that if they have a gun you need to know in case the decide to shoot you is bullshit.
If you are that worried (paranoid) about it, buy a gun yourself or move away from a place you think may be unsafe.
