So if I get this right..
Someone says a joke that offends you, in earshot, but not to you, and you take this as your opportunity to photograph them, get them kicked out of a con, fired, pilloried in public? And then you take to your blog to defend yourself (not really) with an incessant repeating of "I'm in the right! I'm in the right!" (paraphrased)
Let me say this as clearly as I can: Anyone who would engage in the behavior described in the previous paragraph is a colossal fucking idiot of the highest caliber, who I would think very long and hard about hiring or retaining employment for any job that required any kind of public interaction.
I am having trouble mustering words for how angry this makes me. Time to get off the internet for a while.
