Quite funny, and, I'd say, usual.
My language is neither that of polite nor impolite conversation, but the language of reason and honesty.
I do as I can to not be impolite, but when people define "politeness" to mean pretending that their view is wise when it clearly isn't, then even though I wish I could do otherwise I cannot escape this dilemma : either being honest, or being mistaken as "impolite".
No matter if you like to believe it or not, the fact I hardly learned in my life is that essentially all the troubles I went through resulted from trying to trust people, assuming they were wise and trying to work with them or following their advice, while they were in fact dumb or mad. I am just too naive and confident towards people in order to manage. Many things would have gone better for me if I just understood from the start how mad they were, however the problem for me is that such an assumption is extremely unnatural, so that despite all experience I continue falling in more troubles by trying to give people undeserved trust over and over again.
I am aware of the huge troubles resulting from the domination of this world by hypocrites who have so big ego problems (the ego problem of assuming that the biggest evil in the world consists of any hypothesis that someone might think better than themselves, which they misinterpret as the sin of inflated ego of others, since it puts a shadow on their own), which I have to cope with if I want to try bringing some contributions on this planet. However the crude fact is here: the effective progress of science requires to use the language and care for truth and reason, not that of hypocrisy.
If you reply that sciences do not need impoliteness either, well of course, scientists usually do not seem impolite as long as their discussions remain between scientists all able of reason, where nobody has the crazy idea of misinterpreting truth as an insult. But this happens precisely because discussions take place in a community of selected rational people where hypocritical idiots (cranks) were left out. The only way to find useful partners for genuine work, does not consist in attracting crowds of hypocrites who unfortunately aren't able to contribute any good work anyway, no matter if I wish it or not, but it would consist in finding a nonzero number of people who are actually serious thinkers, and who therefore are not in need of any sweet lies and hypocritical language to understand and find the motivation to do the work. Such people may be unfortunately hard to find indeed but even if I wished to, there would be no way to make things work otherwise.
More comments on this topic here, there and there.
And if you think that by being "more polite" it would be possible to better succeed attracting useful partners to do works that can change the world, well, what are you waiting for ? Just go and do it, I'll be very pleased to see the world changing for the better without having to bother working on it myself. You are even free to choose between stealing my plans if they may be good, or developing your own otherwise.
