Adding equations that everyone should know anyway might amplify a
proposition like "Every Boolean algebra is a Boolean ring", but your
suggestion that the amplification logically negates it is remarkable.
In any event I already referred to this context yesterday in case you
hadn't noticed, in my reply to Kanovei agreeing with him that this is
exactly how the correspondence works. I had not bothered with typing
in all those formulas (thank you for doing this) thinking that they were
familiar to everyone. I see in retrospect that I misjudged the situation.
