Take evolution as an example.
One of the major arguments I've heard against it is that there are no observed instances of speciation.
Yet, you type that into Google, the very first link takes you to many observed instances of speciation.
It's frustrating as all hell. The truth is, these people don't want the truth. They have their beliefs and they're not going to challenge them or change them in any ways so when they're confronted with something, such as evolution, that goes contrary to beliefs, they don't investigate evolution, they investigate "how evolution is false." Thus they don't do research properly, they don't search google for evidence for evolution and find it on the first fucking link in two seconds, they search for evidence against it because it has to be wrong! It has to be! It goes against everything he believes therefore it must NOT be true.
If he stumbles upon evidence for evolution, he'll rationalize it and say, "there's gotta be some way that this is wrong."
It's more stubbornness than laziness.
I've read some of the posts Answers In Genesis have put on their website, I've tried to understand them, tried to see their view but also knew through research that they were wrong, but the key is to not be afraid and go to your "enemy" and learn his stance. Maybe he's not really your enemy and maybe he is right? Knowledge isn't about "enemies" or "us vs them" (which is why I put it in quotations in the first place,) it's about understanding reality and to do that, you have to be ready to accept all possibilities and be skeptical of all possibilities and that means you can't toss out a possibility just because you don't want to believe it. You have to investigate it, see if it adds up, see if it makes sense in reality. Only after making an objective investigation can you then decide if it is accurate to reality or not.
