Most likely a bad thing, given similar past examples. E.g. I've talked to atheists who won't touch Bostrom/Anthropic Bias because they associate "the anthropic principle" with theological fine-tuning arguments. And the general problem of audiences' first impression of Bayes being that it's just another clever way to argue for whatever you want to believe or want others to believe.
On the other hand, it would be interesting to have more debates between theists and atheists who are both familiar with Bayes and use it explicitly, if the atheist is good enough at noticing and explaining flawed uses of it, so audiences can become familiar with fallacious uses of it and see that it can be used wisely.
This post grew out of a very long discussion with the New York Less Wrong meetup group. The question was, should a group dedicated to rationality be explicitly atheist? Or should it make an effort to be respectful to theists in order to make them feel welcome and spread rationality farther? We argued for a long time. The pro-atheism camp said that, given that religion is so overwhelmingly wrong on the merits, we shouldn't allow it any special pleading -- it's just as wrong as any other wrong belief, and we'd lose our value as a rationalist group if we began to put status above truth. The anti-atheism group said that, while that may be true, it's going to doom us to be a group exclusively for eccentric nerds, and we need to develop broad appeal, even if that's hard and requires us to leave our comfort zone.
Things got abstract very fast; my take was that we need to get back to practicalities. Different attitudes to religion have different effects on different types of people; we need to optimize for desired effects and accept what tradeoffs we must. We can't appeal equally to everyone. So I came up with a sort of typology.
