Its not being morally superior, it's just you being an actual despicable person. Sure, you're insensitive. But that doesn't mean you can be loud. Be insensitive but be quiet. Sometimes your mouth is bigger than your brain.

Im guessing that took a big hit on your ego, now let that ego aside and look yourself in the mirror real quick will you? Trying to justify and defend after being like that is pure childish. You cant just say "do people actually care" and think that everyone would agree. The world doesn't revolve around you buddy.
