The mere fact that you post things and chat with your friends, dog stuff only or not, will give them an indication of your political leanings, if only slightly. Enough for an educated guess apparently.
I, on the other hand, had no politics section or no political affiliation shown for me in the "Your Categories" section.
Like I said before, they don't know me or anything about me because I refrain from posting stuff, writing things and clicking on "Like" buttons and such.
The reason they know you are conservative, is the very reason I don't send any signals to them about who I am. I don't want them to know anything.
It's been over 12 years on this FB page and nothing has ever changed. It's like I don't even exist to them.
Which is perfectly fine with me.
Yeah there has to be something along the line that I did, and perhaps do not remember, that revealed me as such.
Because I generally do not talk politics anywhere. I am as incognito as I can possibly be, no bumper stickers, no yard signs, just nothing. I don’t want anyone to know what i think on such matters, except for my closest friends who do know that information.
