I’ve got people on my Facebook from both sides, conservative and liberal, so it seems to balance out on my page. I enjoy engaging the libs to keep them riled up. Both sides of the spectrum come from friends from high school 40 years ago. I don’t generally get overly political in my original content but it does come out in my responses.
Heck you don’t even have to make comments.
Some “Friends” will notice if you don’t “Like” some pro-sodomy comment or link. I had one unfriend me because they noticed I never “Liked” any of their liberal propaganda that they posted.
