What is
wrong with the
idea of heaven, hell, blah blah blah is the people who wage wars, kill, maim, insult, and otherwise try to impart their way
of life on others all in the name
of religion.
But, also, any human with common sense knows that at this time, all
religions and creeds known to men - are full
of crap and instill separatism among groups
of humans as if one is more valuable to God - they guy who supposedly made everyone and everything - separatistic
ideas as «my book» my god» «my people» are the most beloved by God are
wrong, will be always
wrong and all
religions are
wrong and will always be
wrong.
As Steven Weinberg points out here, the argument made against extremists ends up invoking a moral sense to argue that the religious
ideas of the extremists are
wrong, when the whole point
of religion is that it should be the other way around.
