I have issues with all religions period because it inevitably becomes corrupted (and I am not prepared to 'have faith' in something that clearly doesn't have the power, or alternatively doesn't care to prevent all the terrible cruelty and injustice that exists in the world), of course the problem is really just human behaviour.....
Exactly. Your problem isn't with Religion, but the people that abuse it. By that same token, this is me as well. As flawed as I think Islam is, I really couldn't single it out for issues, all the big abrahamic religions have their issues, some more than others, but still.
Thing is though, it's the people that put it to practice, the people that bend it to their will to serve their purpose. You (and I) wouldn't have a problem with it if Kings hadn't murdered to be able to edit what they wanted in holy documents, if they hadn't changed hands and been altered time and time again. That's not religion, that's the people. Religion itself has brought us culture, laws, civilization, all of that and its only real flaw is that religion can be interpreted in so many different ways, and the holy documents and literature don't have someone around to say "Canon". And even if it did, the canon may not always be good. Such as the Qun, which is very rigid in its interpretation.
But one would have to be rather intellectually dishonest with oneself to say they hate religion, especially when there are many religious practices that did not lead to war and corruption. It's the big ones that were used by leaders and those with money that were abused the most.
Anyway, to relate this to Solas, Solas may hate the Qun (more doctrine than religion), and that may be the same as hating those who follow it like sheep, but I don't think so. Like what was said, he seems more cynical about Bull than anything else. You can hate something about someone and not hate them. Just to reiterate.
