Hmm I see someone had a post deleted. What's it like to report a post? Only I have never done it and I have been called lots worse. I'm a man so I am by default a rapist, pervert, violent, nationalistic, brute who invented slavery and misogyny :)
Anyway, regardless of how you say it all religions ARE irrational - unless you're the guy who invented it to gain control. As I've said many times the members of a religion are also usually victims of that religion. Caught when young and vulnerable. Taught by people they should have been able to trust (who in their turn were often victims) they had no chance to see if for what it was.
That should make it more understandable, but doesn't excuse it entirely. It's up to every adult to examine their own behaviour and decide if it is correct and if there is a better way. If we didn't do that we'd still be hiding from the thunder.
Religion teaches people to do odd and sometimes nasty things, but worse still it teaches them a method of deciding what is sensible and good. A combination of what the holy book says, what the priest says and what urges come into your head if you scrunch your eyes closed and press your hands together (or tap your forehead on the floor, or bob rapidly from the waist or dance in a circle stamping your feet to a drumbeat)
The main religions emphasis not thinking. Faith is a virtue. Thinking is doubting and if you feel the urge to doubt you must perform some repetitive motions and/or chants until the urge to think goes away.
