It's distracting and offensive to people who have spent a lot of time and energy thinking about this stuff, and more importantly it causes confusion in the public eye. Phrasings like "weird hemming and hawing" suggest that we don't know/don't care about some insight you have, which is not true. This is why your posts are FUD. For example, in your linked post I looked at every single instance of the character 'k' and *not one of them* defined the value 'k' from which 'R' is derived in the signing procedure. Of course there is no possible value, individual signers cannot learn 'R' at signing time without interaction, and your whole scheme is broken. Given the number of times you've been told this, I find it hard to believe that this was an honest mistake.
