The Web series leans more towards fanon than canon. The target is those fans online who like the tumblr interpretation of the Batfam. They take a good deal of inspiration from batfam internet communities. Incorporating popular HC's into the series.
I disagree that fanon only cares about easy rtp point's and that fanon doesn't have Damian interact with his heritage.
Fanon often has Damian embracing his heritage. There's a lot of content out there that centred on Damian as Arabian to the extent that hot only does he converse in Arabic he even celebrates Ramadan. It seems to the internet Arabian must mean Muslim.
It's lost on these fans that by viewing Damian as and head cannoning him as just Arabian and come Bruce, they are displaying racist behaviour. Erasing the character's actual ethnicity. Like the Chinese and White parts of him aren't worth consideration.
I suppose reducing him to just one ethnic group they are simplifying him. Making him easier to stereotype him and slot him into a box.
