i definitely understand people's frustrations with ocs, especially ones where the main focus is hooking up with a canon character. most of these are avoidable though, i believe? it's usually fairly obvious when there's going to be a cringe worthy oc/canon story based on the summary
(looking at you metropolis section on ff.net and that's including my fanfiction). on deviantArt it might be a bit harder to ignore, if you are watching their account and you can't really filter the stuff with tags like on tumblr, so you're kind of stuck seeing it.
i was just voicing my opinion that it kind of stinks that people are so embarrassed of having ocs or anything like that, even more so if they were paired up with a canon, that they go into denial etc. i think, if the person acknowledges that they're being a little silly for doing so and is rather mature about their oc/canon shenanigans, it's alright! plus, people should look back on these sort of things and laugh about it!
when it comes to shipping, things can be a little muddled and stuff. i ship some admittedly messed up pairings (both crack wise and stuff where it can be kind of [OUT OF TUNE TRUMPET NOISES])

but i know that people aren't comfortable with it so i try to keep quiet about it, so i don't bother people with it.
