You might want to spend some time contemplating whether there's likely to be any relationship between the frequency with which you insult other people, and the amount of effort they are likely to put into thinking about your ideas.
I usually try to limit my insults to ideas, which last time I looked are inanimate objects and pretty immune to such things as feelings.

Oops, maybe that was an insult as well.  I will try to stifle myself, and just consider anything outside the bounds of decent behavior as my attempts at snark (people such as Michael Lynch, George W. Bush, and Michael Crichton excluded).
