I see no reason people can't have their own homes on the internet. I don't let any random stranger come to my physical home and lecture me on my shortcomings as a human being, and I feel no obligation to let randos do that to me on my website or by email.
Of course, venturing into shared spaces like IRC or the Midnight and saying something foolish or offensive is another thing entirely. There's a reason people used to say "lurk more" online. You've got to read the room.
