I posted about alpha, beta and release candidate for laughs, and judging from the thumbs up, several people understood.
But having just read the comments again, several of your arguments just do not add up. You've used the fact that MS Office sells in large volumes to justify it's goodness, without taking into account the self-perpetuating dominance that Microsoft have on the market. Many copies are sold because of FUD or momentum, not because people make a reasoned comparison.
You've also effectively said that because you understand and were willing to learn the ribbon, that anybody should be able to, and if they do not, they are lazy or in some way intellectually challenged. That is far more insulting than anything I've said, including the alpha, beta, rc jibe.
I have said that change taxes some people, but I've experienced lots of people who just don't understand why this constant churn is necessary. They get bewildered by the huge range of options, menus and inconsistencies between packages and different versions of the same package. This is not because they are stupid, but because they use computers as tools rather than the computers being their profession. They want to learn something once, like riding a bicycle or driving a car, not have to relearn it every five years.
The term freetard is very derisive in the way you use it. Not everybody who uses Open Source software is to be scorned. There is much in Open Source that is good, and just because someone gives their work to the community in general is not a reason to sneer. Save your scorn for those people who steal other peoples work by not paying for licenses. Of course, it may be that you are one of the people who feel threatened by other people giving away their work for free, but you should only be worried if the quality of the package you write is worse that that in the Open. The answer to that is to either get better, or find another career.
I buy good software, and all of the music and other media that I consume. I use Open Source because it often does the job I need, and saves me money. I don't steal software, movies, music or books.
I find the poor grammar, and lack of correct capitalisation in people's comments notable. I equate it to people having an unreasoned rant, and not taking the time to consider their use of English, which I extrapolate to mean that they have probable not considered the content of their comment either. This was the cause of my 'foaming at the mouth' comment.
You come across as dogmatic, condescending, and often arrogant. If you came across like this during a sales pitch, I would probably quietly show you the door, regardless of whether you tried to impress me with the quality of your designers, programmers, or the result. But I respect your point of view, even if I don't agree with it.
The fact that you can't take criticism, or reasoned argument without descending to insults (and you've done this more than anyone here) probably indicates some type of insecurity.
I'm leaving this particular set of comments now, because I don't think I have anything else to say without repeating myself.
