They want to have it both ways, to say it's ulimited for marketing purposes, when there are in fact limits they just don't make available.
Sending a message back in time from your own perspective does require bouncing it back from a moving reference frame to my knowledge, but is a valid consequence of FTL communication within special relativity.
Stop assuming you already know everything and can dismiss anything you don't understand; it just makes you look stupid. You don't appear to have even heard of special relativity beyond the word "observer", so I'm not sure why you think you can overturn the work of pretty much every physicist who's looked at the subject beyond unwarranted hubris.
Functionally, quantum entanglement is the equivalent of placing single red and blue balls in separate boxes without looking at them, sending one box to China, and then opening your box. If it's the red ball, you now know the one in China is blue, and vice-versa, despite the great distance between them.
Now mechanically, the quantum equivalent is considerably more exotic, and involves either instantaneous transmission of quantum states or hidden variables that predetermine the result, but as far as actual utility, it's the same thing, and you can't use it to actually send any new data.
No, they aren't. I would suggest that you haven't been paying as close attention to the quantum computer "malarchy" as you think....
Interestingly, the proposed end-state Communist utopia is pretty much the same as a Libertarian utopia, if you strip out the buzzwords. The totalitarian stage (even if it's never been implemented exactly as Marx envisioned) is explicitly not the end goal, but envisioned as a necessary step along the way. Of course, no attempt in the real world has actually gotten past that stage, just as the efforts of economic libertarians are likely to just leave us stuck in a state of dystopian corporate feudalism if actually implemented.
If on the other hand you're mad that there were captains who weren't white males, you're just an idiot. Janeway's problem wasn't that she was a woman, it was that she was a badly developed character, with an actress whose voice could grate cheese.
