Oh, I misread you. Often meaning and purpose are used as synonymous terms. I assumed that's how you were using them, so when you went on for a few paragraphs about how nothing has objective purpose I assumed you also believed that everything is meaningless.

Still, I don't think you've actually presented a good argument for suffering being objectively bad. "Pinch yourself," you say. Well, I did pinch myself. Many times, willingly, even knowing it would hurt, though not to an unreasonable degree. What exactly is that supposed to prove? Is an aversion to something a sign that the something is intrinsically bad according to you?
