I never implied on this thread that anyone could send an FTL signal to anyone else.

What you said was that in your understanding, FTL effects need not lead to causality violations. What I was attempting to show (to the interested reader, whether or not that describes you) was that FTL communications do indeed imply the violation of causality, and not in some abstract, technical, "on-paper" sense (which is what I thought you meant by a "Feynman-Wheeler" sense), but in a practical, technologically exploitable ("Finney-Wells") sense. So strong is the connection between the speed of light and causality that in physics papers the terms "faster than light" and "causality violating" are used interchangeably.

The Finnish gravity experiments you read about appear to imply the possibility of FTL communications, gravity propagating instantaneously as it does. You gonna send the causality police off to Finland to arrest the guy?

Ah yes, of course. Well, this is indeed a deep subject for you, and it has been a fascinating conversation. Have a good night.

Phys, because of your intelligence, and your obvious knowledge of the subjects about which you post, you've been remarkably immune from scathing assaults launched by some of the many rotten-nasty anti-rationalists who hang around looking for opportunities to spill bile. But now that you're in the arena, let me suggest one guiding principle: You gotta know when to hold, know when to fold, and know when to walk away.

This does indeed (which is clearly language used by you in a rebuttal attempt on some physics assertion of mine) show that you are manufacturing strawman disagreements for the purpose of insinuating yourself into the shallow appearance of correcting me. Look closely at your choice of words, and contrast them to mine. If you still can't see and admit it, then don't waste my time again. On the other hand, you did use the creative phrase "too-subtle-by-half", leading me to believe that you may be frequently letting the house pets onto the keyboard.
