EGG, do post on. It's unfortunate you feel the way you do, even if understandable. This is the only forum I come back to. It's got smart people; it's got funny people; I actually like interacting with the people who are here. Even as a part-timer, and a remote one at that. Meeting people in person will always make a huge difference. For me that's just difficult. I still like this space as one which is informative and entertaining for so many different things, not just how to get an upgrade.
Possible you'll feel slighted or offended, or amazed that a comment you made in jest or good faith was taken the wrong way? Absolutely. Agree with DW, way of the written word. There's legions of academics make a living figuring out what people mean when they write stuff. For good reason - it's hard! One word - 'no' - can seem extremely harsh. Yet, applying a principle of charity, what are the chances the person saying 'no' actually means any ill will to you? They may not want to be your best friend, but dismiss you? I don't know. Still doesn't feel that good to a lot of folk, I'm sure.
I don't know that I'd use the term 'elitism' for what happens here. To me, you'd have to assume that someone not only takes great enjoyment in partaking of things on a regular basis which most of us cannot contemplate from afar (going well beyond the occasional UC flight), perhaps going as far as rubbing one's face in it; you'd have to believe that they also judge you, and clearly think less of you, for not being in the same position, whether by choice or circumstance.
Even if you have found plenty of the former behavior (I don't recall specifics involving you, but I'm sure there were some), I don't know that it rises to the level of being broadly judgmental. I'm happy to think that, when stuff happens, folks are basically just disagreeing with me - not thinking I'm a worthless person. This just feels less of a self-selecting and 'oppressing' forum than FT, allowing for differences in personality. The mods do a good job of rooting out attacking behavior, and most folks seem to be in agreement that they aren't looking for much more in terms of behavioral and content censorship. I do hope you will be able to convince yourself that it's still worth your while to voice your opinions here - it really seems to be worth it to a lot of other folks.
