First off, it's important to point out what the hell faith is. It's a word that's been twisted and shat upon by various groups of people to help get convoluted points across. "But when I talk about my faith I mean my religion" Well then you're just replacing the word religion with another word. I could say "My faith is Muslim" or "My cantology(art of singing) is Muslim" and it's equally as silly. Just because a religion encompasses various forms of cantology and faith, it doesn't mean you should be word shuffling to make your voodoo sound accurate.
Well then what is faith? Simply put, it is believing something without evidence. But it's even more philosophically honest to say that faith is a belief held on bad evidence or no evidence at all, bad evidence being an important distinction later on. Also important to note is the fact that beliefs and faith are not mutually exclusive. Anyone is free to believe anything their mind can come up with. It's what you base that belief on that dictates whether or not other people on Facebook are going to mock you with impunity. Basing your beliefs on solid grounds is good and basing your beliefs on bad or no evidence is bad. Making important decisions based on hunches and faith is an irresponsible way to live your life.
Which leads me to the main point.
