It portrays it in both ways. While the worship of many gods on old-earth, or our Earth, is what first gave rise to the Chaos Gods, the spread of a single religion (the Imperial Cult) is said to spread order, and therefore rebuke the Chaos Gods. Hell, according to some sources, the unwavering faith the citizens of the Imperium have in the God Emperor is the only thing keeping the Chaos Gods from ending all human life.

Any secular liberal who isn't pro-LGBT and Pro-female priests isn't deserving of being called a liberal. And the fact that people such as yourself accept and support such ideals is a good thing, regardless of their religion (or lack thereof). But your argument is like someone who saw a picture of slave leia attempting to argue that Star Wars is bondage porn. You know nothing of the universe, the characters, or the deep meanings in the 40K universe, instead judging it by some tiny piece of knowledge you most likely received from a biased source. It's like if I were to read a single passage of the Old Testament, and base my views on Christianity exclusively on that passage. It would be silly, wouldn't it?

The ironic part is that I've had this argument with atheists, who argued that they disliked 40K because of the obviously pro-Christian message, with the God Emperor representing a Jesus figure, leading humanity into salvation. It's silly how quick people are to dismiss something when they see a single element they don't like, unwilling to investigate or understand the context it's placed within.

Edit: Read your second reply, which I originally didn't see. If you wish not to continue this conversation that's fine by me, but personally I thought it had remained civil up to this point, and see no reason why it should turn into anything other than that.
