How to Debate a Muslim?

[Freedom of thought]

As you may know I am from the UK, which has a large influx of Muslims, and I need more information about It so I can debate them.

Same as you'd debate any other religious person. Assert there are cosmology models which do not have a cause(this is in line with modern cosmology). There are models which show the universe can come into existence uncaused or never have came into existence in the first place, all by laws of nature. If they don't think it's possible for something to come into existence uncaused because that doesn't happen in our experience, point out that causality within the universe should be (and would be) very different to causality when you are talking about the universe as a whole. Asserting that causality in the universe applies to the entire universe is a fallacy of composition. If they ask where the laws of nature came from, point out they are moving the goal posts, or asking a question we don't know/or is incoherent. Run the natural problem of evil (I think this is a good defeater for theism, they can't use the free will defense), if they do have a response say naturalism is a better explanation for this much suffering (in a random universe, people are expected to get hurt every so often). Assert morals are innate within humans, from the evolutionary process, and just because its an evolutionary adaptation doesn't remove the meaning of them. Getting along is the only way for everyone to survive/live happy and productive lives, everyone knows this. Point out the horrible verses in their holy book, which allow immoral behavior. Ask them "is something good because god commands it? Or does god command it because it is good?", if they say the former ask them "so if god commanded you to molest every child you see, it would become a moral obligation?" if they answer yes then it exposes their fallacy. If they say the later, it shows they don't really believe divine command theory, they use their own morals to evaluate actions by there consequences.

Now, here are some common bullshit which almost always come up when debating religious people, the average religious person will run multiple incoherent arguments because most of them don't care if they commit logical fallacies: "You just hate god!" Reply: "I can't hate something I don't think exists". "What's the point in living if there is no god to give the universe purpose? The universe will die and nothing will matter!" Answer: "Your emotional response has nothing to do with the truth of your beliefs. But yes, things matter, and they matter now. If you found out god didn't exist, you'd still live your life just as much purpose as you did yesterday." And the list goes on. Whenever someone tries to inject emotion or personal attacks like "you hate god" into it, point out their bullshit, tell them why it isn't valid, and try not to be too much of an asshole. One time I got into a debate with an friend, he was giving out so many non sequitur arguments, I said that his god is a genocidal monster, he got a bit upset and blocked me. As someone else said in this thread abit of snarkyness here and there never hurt anyone. If necessary, the only snarkyness should be when using humor to point out the absurdity in their position, humor is very effective most of the time.
