I myself am an Atheist so the last few points don't really make me feel anything apart from being confused to why you put it in there , True that some meanings have been lost in translation. But we should remember that this was all around about 1400 years back and all of this back then was considered fine and fair , We should all be sane enough to not do these acts but there still are groups and people doing these acts . If a few people are doing bad things it does not mean you should out bad light on all of the religion.
