It's quite well known among skeptics how much apologists, especially young-earth creationists, lie and how hypocritical they are about it (in other words, while still feigning honesty and sincerity.) However, I got a kind of epiphany of how deeply-ingrained this is in them during a lengthy email conversation with some young-earth creationists recently.
Most apologists, and especially most young-earth creationists, have been brainwashed – and have brainwashed themselves – so thoroughly and so deeply that distorting, misrepresenting, misleading, hiding facts, fabricating facts, rationalizing and outright lying is like a second nature to them. They are so brainwashed into it that they do it willfully and purposefully, yet they still don't realize they are doing it, and convince themselves (besides trying to convince others) that they are being honest, sincere and truthful.
Just as a small example, one of many, quote mining is a very common practice among them, and one which dishonesty is very easy to understand and see. It doesn't require much intelligence and thinking to understand why quote-mining, for example, a big critic of creationism and proponent of the theory of evolution to make him or her sound like they are either supporting creationism or attacking evolution, is quite dishonest.
Even if you heard such a person say something that seemingly goes against everything else they have said previously and afterward, the proper reaction that would show honesty and intellectual integrity would be to ask "what did he mean by that? Am I missing something? Is this perhaps taken out of context? What else did he say in this situation?" In other words, the honest reaction would be to try to find out if they really meant what they seemingly said, or whether it was something else, in order to avoid misrepresenting what that person really thinks.
But that's not how the creationist mindset works. Any utterance, no matter how out-of-context, no matter how disjoint from everything else that person has said, is good enough for them. It doesn't matter what that person really thinks or what they really mean. If it can be used as a weapon against that person in particular and the opposing view in general, it will be used.
While at the same time claiming that sincerity, honesty and integrity are core virtues of Christianity.
And the sad thing is that they don't even see themselves what they are doing. Even if there's a small voice in their mind that says to them something like "hey, perhaps this is not the most honest thing to do", they quiet it and don't listen to it. They don't want to think about it, and subconsciously they maintain a mentality that the end justifies the means, even if it means distorting what others have said (even though they wouldn't admit that even to themselves at a very conscious level.)
They have become so used to this via years of practice and "training" that they have become masters at deceiving themselves. They truly think that they are being sincere, while being blatantly and obviously the opposite.
This is what religion does to people. It distorts their personality, behavior and morality. It makes them do morally condemnable things while still thinking that they are morally pure and superior.
If the god of Christianity really existed, and if he were such a perfect being, I'm sure that he would be shaking his head in sadness seeing these people acting in this way in his name. Even Christians should be ashamed of creationists (even though, sadly, most of them aren't, mostly because of ignorance or a deluded sense of camaraderie and duty towards their "fellow believers.")
There are actually some atheists who were Christians in the past and who started to doubt and to find out how things really work mostly due to being fed up with young-earth creationists. (Many young-earth creationists actually try to "convert" so-called old-earth creationists into becoming young-earth ones, and to some Christians that can be a real eye-opener, but in the opposite direction than the creationists expected.)
