Edit: fix unclear wording, add question

All that remains is to argue over whether or not that exception was merited, and "it was just a joke, god, why are you being so emotional, jeez" - another uncharitable but accurate paraphrase - doesn't strike me as much of an argument. Neither does, again, claiming that I must be lying about what people did, or how many, in response to that comment of his.

Would you please step up your game? Answering the same tired objections over and over again, as they're reiterated in slightly different ways, grows dull, and it's difficult to distinguish one's interlocutors from one another when they're all saying the same things.

Except it's not.

You're misinterpreting his joke.

It is a joke, but he's saying that:

1 - keeping the lights off is conducive to having sex

2 - although he might enjoy sleeping with some of the people in the room, that's not what they're there for

3 - instead, he would prefer to see the audience

4 - so he's asking for the lights to be turned on

Are you really sure that's a place you care to stand? Because, whatever you may think you're saying, that's how you're being heard - and how your audience hears what you say is not a phenomenon subject to your control, or RMS's.
