But the content in my post isn't by Less Wrong, it's by McGrayne.

Fair point. Still, a person who hasn't read the book can't know whether lines such as "at age 62, Laplace — the world's first Bayesian — converted to frequentism" are from the book or if they were something you came up when summarizing.

If they want, they can check the notes at the back of McGrayne's book and read the original articles from people like Fisher and Jeffreys.

In previous discussions on the topic, I've seen people express the opinion that the fierce debates are somewhat of a thing of the past. I.e. yes there have been fights, but these days people are mostly over that.
