The problem with the faithful of *any* religion is that it is, by definition, they are unreasonable.
The religious have closed their minds and decided that everything there is to know is already known and their particular prophet has already had the last word. Such BORING people.
And so susceptible to influence. It is because the religious are intellectually and philosophically bone lazy. The want their morality to be spoon fed to them.
Any day I have far more respect for a free thinker whose position I vehemently disagree with than any mindless, boring, lazy, religious devotee.
