S47 you are a poster who just keeps on giving:

You are scaring me now, I have a nasty feeling you might find me a heckler, but happily there is a perfectly good ocean between us: people IRL do respond to me in ways that make me uncomfortable. I'm starting to see them as hecklers What do these hecklers say? I imagine you have some pretty crushing responses?

I confess to being a tiny bit disappointed that you don't seek feedback from a trusted friend (straight feedback not heckling) in RL, as I had rather set you up a role model. I have German friend who reports that in Germany friends will be straight with each other. This approach proved extremely unsuccessful when applied to his British friends.
I rather like to imagine the German version conversation: "Ja, Ja, Gottlieb, I am certainly a bitter, sarcastic, bullying schwienhund all right, thanks for telling me, let's go and watch the match and see the Englanders get beaten 0-8 by Deutschland again".

However, it is probably about time I answered your question; You seem an OK sort of fella, but then most people are if you take them as you find them and don't expect to much.
