Faith means making a virtue out of not thinking; out of ignoring reason and facts.
Faith must be represented by answered prayers, divinely-ordained morality, heavenly warrant for circumcision, the occurrence of miracles ad-ridiculous-infinitum. It keeps mankind in a bondage of ignorant arrogant certitude. It allows human beings who don’t think that they have all the answers to think that they do.
Attributing to God that which we don’t understand is our first, and our worst, attempt at explanation of things that are not immediately obvious. It is how we came up with answers before we had any evidence. Physics and chemistry and biology and palaeontology and archaeology have, at a minimum, given us explanations for what used to be mysterious, and furnished us with hypotheses that are at least as good as, or very much better than, the ones offered by any believers in other and inexplicable dimensions.
“Faith” is a cop out excuse to believe supernatural myths that cannot stand up to the empirical and experiential methods that establish knowledge used in every other aspect of life.
False though the idea of “god” is, it has caused the slaughter, maiming, oppression, and silencing of millions throughout history. It suppresses science, inhibits education, distorts politics and provides cover for extremists. Christians, Jews, Muslims, and others are absolutely convinced that their beliefs are the The Truth and all others are necessarily wrong. The particular stories of primitives who lived thousands of years ago that one believes are merely an accident of birth and brainwashing.
If you joined a social club that was tied to as much bigotry, misogyny, violence, homophobia, and sheer ignorance, you would resign in sheer protest.
