CJ: Well let me put it this way, who is going against it? And what is the it, something or someone else? This perspective sets up you and evolution as an unconscious process as oppositional forces, but clearly that is also you if you acknowledge you have that kind of tendency, right? So I'll go with the part of being aware of it, but by going against it you are essentially going against yourself. You can be aware of it and simply distinguish between a part that is interested in reason and the instinctual part that wants to justify irrationally. Depending on what's going on internally "against" may just be a matter of semantics, but people do get into that whole kind of inner conflict, which just means you're arguing with yourself instead of someone else.
On a more practical note, it's important to be aware of the emotional piece. Disagreeing does not have to mean going against anything, if you were having a conversation with a little kid who obviously doesn't know better you're not "against" that kid in some oppositional way, and our instinctual tendency to justify things to preserve a sense of self can be viewed in a similar way.
