The people who hate OC X Canon so much to the point where they'll attack the OC's creator over it are the people who make me feel ashamed for shipping OC X Canon. The fear of being attacked is especially hurtful for me because some of my OC X Canon ships are major comfort ships of mine and have helped me cope with certain situations in my life, and feeling ashamed of these ships just hurts me even more. The only reason I don't just go and hide or get rid of every single one of my OC X Canon ships is because when I tried to do that, I felt even more sad and ashamed of myself. In fact, a good chunk of my OC X Canon ships are still kept a secret because I'm scared that people will come and attack me because the ships are "cringe." I just want to be able to express myself and have fun with ships, but it's hard to do that when I'm almost constantly paranoid of getting attacked by a rabid OC X Canon hater.
In fact, one of my comfort OC X Canon ships that would be considered "cringey" has already been tainted by hate, and now I can barely publicly interact with the ship without feeling ashamed and paranoid of instantly getting attacked over it. The worst part is that I was already embarrassed about the ship and had a hard time finally admitting to YouTube that I liked the canon character and enjoyed shipping my OC with them (because for some reason I felt the need to do that back then), and while the hate wasn't as overwhelming as it has been for others shipping OC X Canon, it still damaged me because I was already really sensitive and embarrassed about the ship. The ship itself still makes me happy and can comfort me sometimes, but I just tend to feel uncomfortable when interacting with it nowadays thanks to my paranoia and past experiences. The moments where that fear and paranoia go away so I can happily interact with the ship without feeling scared or weird are fairly rare.
I completely understand why people wouldn't like OC X Canon, but just because someone doesn't like OC X Canon doesn't mean that they suddenly have the right to go and put down the people who do like OC X Canon. Yes, OC X Canon can be cringey, but so what? Everybody likes or does something at some point in their life that others would consider cringey. Just because somebody thinks that someone else is "cringe" doesn't mean that they can just go and attack that person. Just let people enjoy themselves if they aren't hurting anyone, it's not that hard!
