"every one of Gmail's outbound VIPs is in a SORBS blacklist. Every one I checked is in at least 20 other blacklists"

I still don't understand your statements. That's simply not true. It's not even close to being true.

Post a Gmail outbound VIP that is not in a SORBS blacklist, then, if you're so sure.

Whatever the opposite of a disclaimer is: I was the tech lead of gmail delivery SRE for four years, so it's likely that I know more about this topic than anyone on this board.

Seems to be mostly not listed?

Sure but blacklists are binary. That’s why they don’t work.

It's perfectly fine to check 282 blacklists and treat only N hits as a positive?
