Great post!
The only thing I can comment on is about scientists not wanting to upset the Einstein applecart. Nothing could be further from the truth, and in fact, scientists continue to attempt to verify predictions of Einsteinian relativity. One of those predictions is that a spinning mass will drag space with it, and there's a satellite being launched soon that will study this effect. This research project was recently scooped when a pair of scientists announced that analysis of satellite orbital positions over the past 20 years gave results consistent to within 1% of the predictions of relativity. They say they're currently working to improve the accuracy, because if the 1% error bars turn out to be an actual difference it would be a huge nonconformity that would mean that Einsteinian relativity would have to be modified, and it would be a sure Nobel.
You don't win Nobels by blindly adhering to existing theory - you have to make an original contribution. The race has been on to prove Einstein wrong ever since his 1905 paper on special relativity and his 1916 paper on general relativity. So far Einstein has been winning, but that doesn't mean he'll win forever.
I agree you received harsh treatment - I had a negative reaction to the post that seemed to assume we needed an education about relativity, and maybe some others did, too. The relativity paradoxes
*are* difficult to think about for many of us, myself included, but over time I've formed my own set of personal visualizations and analogies that have been very helpful.
