Stating, or even contemplating most ideas will piss off somebody. In general, the nasty invective is inverserly proportionate to the commenter's ability to counter your logic and/or the degree to which they are forced to question their basic axiomatic beliefs.
In other words, it's a sign of success.
Along roughly the same lines, here is what the epigrammatist Martial says about annoying one's readers (Epigrams 6.60):
Laudat, amat, cantat nostros mea Roma libellos,
meque sinus omnes, me manus omnis habet.
Ecce rubet quidam, pallet, stupet, oscitat, odit.
Hoc uolo: nunc nobis carmina nostra placent.
Here is a not too free translation by James Michie:
All Rome is mad about my book:
It's praised, they hum the lines, shops stock it,
It peeps from every hand and pocket.
There's a man reading it! Just look --
He blushes, turns pale, reels, yawns, curses.
That's what Iím after. Bravo, verses!
Finally, just because I particularly like the translation, here is Dorothea Wender's version of Martial 8.76:

"Please, Marcus, tell the truth", you say,
"That's all I want to hear!"
If you read a poem or plead a case
You din it in my ear:
"The truth, the honest truth!" you beg,
It's damned hard to deny
Such a request. So here's the truth:
You'd rather have me lie.
