I left forever a dictatorship at 15 because I could not immagine my future in a place - a country - where I had to sing with the crowd or else suffer the consequences of having different ideas - and I did have different ideas. Since then, I lived in one of the most democratic countries in the world, a country where we vote even for futile things like cutting down an old tree or not, a country where everybody is entitled to have and express his opinion and a country that I limitless respect.
This is exactly what I've done, starting with "Personally" and strictly sticking to my point of view, as biased or wrong as it might be. It is, and remains, my opinion. And every opinion, especially if it's different from some kind of "established truth", can be the starting point of constructive, mind-opening, horizion-widening dialogs - or can be flushed down the toilet by the first know-it-all dictator around. Other criteria, like political correctness, the desire for social peace and tranquility or the need for perfect harmony at any cost might refrain others from stepping in - but then the whole concept of forum becomes useless, because as nice as it might be to stay silent together, there are other places and times to do it.
Staying together in this forum and turning each day into Christmas, New Year's Eve or Thankgiving is not going to work in the long run. We can't go forever celebrating new members and wowing at each other's new amp or piece of hardware; I personally need healthy discussions from time to time, discussions which bring excitement, new info and ideas, different points of view et similia - but getting answers that begin with "it's patently untrue" and continue with "you're a victim of misconceptions...unbelievably condescending attitude" is not what I was waiting for - it's exactly what I've been running away from my whole life, and my running shoes are always ready, should I have to put them on again.
