A lot of people who are regulars here have actually met in person and correspond outside of this forum. Not everyone are “internet strangers”.
I was kind of talking specifically about you. You don't know me, you don't like me, so why do you care that I don't like Led Zeppelin? Even if I say it in such a mean way. Again, if you were to say, "The movie Citizen Kane sucks", I would not be calling you a troll or any other names. I might try to refute it. But it would not bend me out of shape.
Note, I have added a new disclaimer.
