Just a friendly observation, because I see you're new here, and maybe hadn't caught on yet.
People who start their argument with a juvenile "Dude" give the impression that what follows will be similarly juvenile. Their subsequent comments are discounted accordingly. Unfair, perhaps, but nevertheless true.
I must also note that it is not at all uncommon to see a post that begins with "dude" ending up with a call to legalize marijuana. I see you've maintained the trend.
Thanks. You're right. I stand corrected as to etiquette.
