I'm on FB and I haven't given them any personal info - no birthdate, location, where I graduated, anything.
It's simply for me where I have a little connection with old friends. I NEVER post any personal info on me or my children.
FB is what you make of it. It seems to pull the inner narcissist out of most people. And yes, Zuckerberg is a leftist tool.
But your name is there?
I might join under an assumed name if I needed to see something there but that would be a very rare occurrence.
My youngest sent my brother a picture via email or text, of the first deer he shot and my brother posted it on FB..... I had a $h!t fit and made him remove it immediately. There are tree huggers (and any variety of leftists) out there looking for people to vilify. No sense advertising.
