The favorable face of politics has usually been rich older white male protestant lacking diversity and limiting the progression of all the rest of the population.
The Right-winged Christians and other extreme religious people have denied the civil rights of the minority, whether it was the enslavement of a race or the continued denied marital rights of the LGBT community.
So many wars have been started (the holy wars), lives have been taken (those of the LGBT community who have been killed or have committed suicide from religious fueled gay-bashing), and the future progression of knowledge has been stifled (by those who jailed Galileo for his realization that the earth revolved around the sun, and creationists who teach children that the theory of evolution is a lie).
And I don’t like how everyone has missed the whole point of religion. It’s about relating our humanity to spirituality and to following moral values that establishes one should be treated like you would like to be treated. Religion is about finding peace, loving one another, and being better living beings in the process, but no one ever practices religion in this way. Instead, they use religion as a weapon to build higher barriers and to keep anyone who is different from them away. I mean—who cares if she’s black and he’s white, or if that guy is gay and she’s straight. We’re all people and we should treat each other like people regardless of what any one religion has told you.
