I only have FB to play Dragon City, so I wasn't choosy about who I'd "friend". Then, I discovered some of the people were posting racist, bigoted and hateful photos and videos. Those people had to go. I can disagree with you politically, my own brother is one of them and we are very close.
About me: I must react to bullying or hate speech. I say my part then, for me, it's done. Others cannot let it go, so they have to go.
I've had a FB problem with muslims trying to convert me from Christianity, as well. Call it whatever you want, but it got to the point that if you write in Arabic or your name is Muhammed, I won't be adding you to my FB. I'm not talking about someone who tells me about their faith... I have my own faith. Spamming, however, or abusive posting was becoming rampant. I had to take drastic action. I am only there to play ONE GAME.
