They may be nice about their objection, stating that they just think this is the way it is. But they still make no real argument for or against the proposition. They state a position as if it were a fact, but they give no valid evidence or reason to back it up. Any evidence to the contrary of their position is simply written off with no thought of actually considering it. I think we are seeing this more and more.
Logical argumentation is a difficult process.
It requires critical thinking. It requires challenging our own thinking and attempting to formulate a position in a logical and concise manner. It is much easier just to object and leave it at that, feeling frustrated because the other person is just being stubborn. And the discussion ends with no one improving for the better. You may wonder what this has to do with apologetics.
