I am a progressive, left-wing libertarian Christian. I love Christianity and I think its great, because it has been getting good updates from society and became more up to date with 21st century morality (is this good? debatable). Anyway, of course some of god's horrible fan club (right wing, extreme anti-liberal and anti-accepting Christians who keeps on hating African Americans, Jews and reason) are ruining this, but overall its good-but I am very biased. If Christianity didn't exist, I would have to say that Islam is my runner up. Then Buddhism. Then Judaism, because I don't like how Judaism discriminates against anyone not Jewish.
Anyway, its debatable. This is a quick perspective/rant. Thanks for reading.
