"I hated that Batman hit his kid in--"
nope stop right there. i'm going to give you a wonderfully freeing bit of comics fandom knowledge.
batman didn't hit his kid because batman isn't real. a writer wrote a fictional character hitting a child and an artist depicted it. if i defend batman, i'm not saying this act as a concept isn't gross, or that it's excusable-- i'm saying it's so reprehensible to me and incompatible with my preferred Batman shape that I'm stepping outside of the universe and acknowledging that this is a fiction created by people who might have done it badly (or differently than I would like, but not my cup of tea).
"but it's still canon--" this isn't a book series. this isn't a movie, or a show with a few seasons. comics are different. they're so incredibly different. it can't all be canon and cherry-picking isn't some mark of failure to accept "the difficult parts." in canon, dick let his siblings believe he was dead. in canon, superman spun himself a cocoon. in canon, alfred died and came back to kill bruce. in canon, bruce cloned himself. in canon, riddler tried to kill a baby with a ping pong ball. it's all canon. it can't all be canon. in canon, bruce retired to europe and never had a robin. in canon, bruce did a trapeze act on a cruise ship to try to impress lois lane.
comic book fandom is like the wild west. some of these towns are lawless, some of them assembled a functional community; the circuit judge has been murdered and the rangers left to join a war effort and some cowboy friends will teach you lasso tricks and some towns are going to hang a man for drunkenly riding away on the wrong horse. you get to pick where you go and where you stay. nobody is obligated to rationalize, justify, amend, or defend canon, and some people will go off and only write about the parts you don't like because that's what they find interesting.
it's not ruining batman. it's not ruining your fave, or harming your fave, or condoning things. they're fiction. they're made up. none of them are real. some writers will get it "right" for you and some won't. you aren't required to accept anything that comes out of the 80+ year stone soup that is canon.
just enjoy things and let other people enjoy things. if it's the wrong town for you, put your head down and keep going.
