Are you suggesting that I take more words than necessary to make my point? I brook no summaries.
Having said that, essentially yes. Rejecting the hope or possibility of a different way of doing things leaves one with only one course of action: acceptance. To endure cheerfully an impossible situation is a virtue, but surely it's no coincidence that acceptance is also the route that requires the least effort or risk. It's also not exactly a virtue to revel in the bleakness of existence, to delight in the things that are wrong in the name of realism. Perhaps there's also a certain envy that cynicism feels for idealism, as something lost which, though it cannot be reclaimed, can be taken from others.
Perhaps one could summarise my position as 'misery loves company'.
