Everyone is entitled to have their own opinions and should be allowed to post them freely in their personal web-sphere-world. Although I may not agree with their stance on politics, religion, music, morals, human rights, etc; they are allowed to post whatever they want on their own Facebook page, blog, etc.
Note to self: It is NOT my job to be an Internet Troll and educate or rebuke them.
I should be free to post my opinions on my personal page, blog, etc. without fear of being relentlessly attacked for my biblical morals and values, by Christians and non-Christians alike.
