One complaint I've often seen from Christians is that atheists--particularly the so-called "New Atheists"--are rude, disrespectful, and stereotype Christians. Supposedly, a lot of atheists would rather flame you than argue with you, and are inconsistent with their self-proclaimed intellectualism by resorting to insults and smears instead of logic. Let's look at this.
First off, it needs to be said that most Christians don't know how to argue. This itself stems from a basic inability to reason. Here's a secret; do you want to know the foundation of all civilized conversation? Context. Simple context. When someone makes a point, it is logical and mature to address that point. This is how scientists, engineers, doctors, historians, martial artists and other experts converse with each other over ideas. However, when you fail to address that point and either A), make something up that your colleague/opponent did not say, and claim that they said it, or B), take something they did say out of context--i.e., "I accept evolution," "Well, accepting evolution makes you racist, because Darwin was racist"--you have failed the debate and conceded defeat. Why? Because both of the aforementioned tactics are illogical, immature, and worse, dishonest. If you can't be honest, then there's no point in talking to you, because you won't admit that you're wrong, regardless of what the other person says. This stupid, immature, and dishonest behavior is known by many names, but "faith" is the most common one. Here's an example of Christian "reasoning" at work. Below is the exchange between an atheist and a Christian in the comments section of a video covering C.S. Lewis' arguments on free will and determinism.
[The Judeo-Christian god is self refuting. Any being which is omniscient
and omnipotent could conceive of and create a universe where free will
existed and evil did not. If you say that god was required to include
evil in this universe then you are saying that he is not all powerful or
not smart enough to figure out a way to make it that did not require
it. Just because you can't conceive of a way to do it doesn't mean an
omniscient being couldn't.
