I'm probably gonna get a lot of hate but I'm going to say it anyway because im tired and in a mood.
If you want your version of Mc to be a dude go for it.
If you want your Mc to be nonbinary go for it
Mc of any flavor of lgbtqia+ do it!
Do you think me should be kissing Tarra, Simon, or Jenna? Smooch away!
You think the boys should be smooching eachother? Let them smooch!
If you think each lad has their own Mc sure why not
If you think they're all in one big ploycule cuddle pile away my individual!
If you rather pair a love interest with an oc who is decidedly not the Mc ship to your hearts content!
If you're comfortable with the Mc/Caleb sibling thing that's a okay
If your not comfortable with the Mc/Caleb thing that also ok!
If you want to explore darker themes or kinks in your art and fics do it!
It you wanna write an au where Sylus is making out with Ada Wong, Zyane is on a date with Leon Kennedy and Rafayel is getting his back blown out by Chris Redfield that sounds hilarious, write it!
If you rather stick to cannon and make tooth rotting fluff and the like that's also perfectly valid!
Fandom is varied. People who participate and create often create for themselves and sometimes they're gonna create stuff you're not into, and that's fine that what tags are for sweetheart. Don't stress yourself or others out by pearl clutching at every little thing that doesn't jive with you. Simply keep scrolling, don't read the fic, don't look at the art, filter the tags you don't like, block the creator you don't like.
It's not the 20 tens anymore. Fandom purity culture is dumb and makes people not like you.
