You're assuming that Bat-fans like any story where Bruce is an OTT *******, regardless of whether he gets called out on it or not. Either way, we're not enjoying what we're reading. Bruce can be a flawed and fallible human being without manipulating and abusing the children in his care. That's how he was written pre-Crisis for a long time. Or ruining the life of Sasha, who is Rucka's pet character (here she is again over in Wonder Woman), whose entire arc was engineered to have Bruce treat her horribly. Fans can acknowledge that Bruce is a bastard in-story (he totally was), but still dislike Sasha and why the story was built that way in the first place.
Well we know that that would never happen, because Frank Miller has such a raging hard on for Bat-God that that would never be written. That's precisely what people are making fun of: Frank Miller losing his damn mind. This is the story that begins with Bruce making thinly veiled pedophile comments about Dick Grayson and just escalates from there. This isn't a good story to use to make this point.
War Games, Murderer/Fugitive, parts of NML and the OMAC crap are the worst of the worst, and my experiences with Bat-fandom online is that a lot of people don't care for them. I can't think of any other major stories or other media appearances where he acts much worse and people still praise it. BvS is the exception, but we all know how polarizing that is on the characterization front, and it seems unlikely that Bruce would repeat his mistakes in the finite DCEU as opposed tot he endless publication of the comics.
