Oh, I see what the problem is. I was using the word "because" in the sense of evidence. As in, "Jack is the murderer because he has a bloody knife". You were using the word "because" in the sense of causation. As in, "Jack is the murderer because he hated the victim". So, I questioned your evidence sarcastically, and you misunderstood and engaged in a non-sequitor, swivelling the conversation from an evidence-based dialogue to hurling insults for no reason. I gave you the benefit of the doubt and assumed you were still talking evidence, when I shouldn't have. I should have understood that you were no longer having a discussion based on evidence, you were just being pointlessly mean. That's my fault for assuming you were a mature adult.
