About canon X oc (Specific fandom.)

I'm not the type to talk shit about a fandom but when it comes to the red dead redemption fandom and its people shitting about OC X Canon is just crazy, I know Some people don't like OC X Canon but the way you're harassing artist because of it is just crazy. 
I see artists make OC X canon I make OC X canon and then I see a comment on a post about "Oh but Arthur and Mary and blah lbhahh" SHUT YOUR BUMBLING BUFFOON ASS UP BRO. I feel like we're not getting the topic here In the letter in chapter 5 Mary writes to Arthur about how she want's to move on. She sent back the ring HE gave to her. She want's Arthur to find someone else to love potentially elsewhere. Are we forgetting? So yes it's completely fine with shipping An OC with Arthur Morgan. 
It's not that deep bro its a FICTIONAL character with your own original character. grow up if you're gonna be a baby about it.
