I've delt with a slew of such comments as of late that had to be immediately deleted, but I kept one of them up for comedic purposes. A case of classic 1984 double speak. Went along the lines, "you should be grateful for having freedom of speech, so please shut up." Never laughed so hard my entire life. The rest though were so nasty that many Hubbers may have risked expulsion from the site if I wasn't merciful and deleted their ill thought out commentary.
I think writing a Hub on "Basics: How to Comment on a Hub" is long overdue. I never thought I would be the person to write basic 1,2,3 steps for writing in the Hubpages community, but supply and demand compels us to move in certain directions. . .
