My only experience with ABS brakes was driving in my wife's Chevy Blazer several winters ago. The roads were snow covered and she asked me to take the thing for a ride because "something's wrong with the brakes". It was in 4wd Hi and I was coming uphill to a stop sign. I applied the brakes, something went BRRRRRRRRAAPPPPPPPPP and the thing pawed it's way right through the stop sign. Up hill. Wouldn't stop. I tried it again - same response. Put it in 2wd and it stopped. But had to put it in 4wd to pull out again.
I have no idea what would occur on a motorcycle with ABS (not in the snow, of course) but any government mandated safety feature on any vehicle just removes a little more responsibility for the driver to actually learn how to drive.
I don't think I'm "for" this one.
