Interview With The Vampire is a show about fictional characters in a fictional universe with gore and sex and violence and blood and love and hate and all of that. Some people are in it for the sex and hot vampires. Some people are in it for the violence. Some people are chill with seeing the books' more out there material be adapted onto the screen.
And hear me out. Not wanting to see incest doesn't make you less of a fan. Of IWTV or gothic media in general. But there's murder! I hear you cry. There's prostitutes and racism and again, murder, abusive dynamics on screen, yet you draw the line at incest?
To that I say, it's fiction.* Fictional murder. Fictional characters kissing. Though, a son and mother (whatever Gabrielle is, good for her) kissing is not my cup of tea, if you enjoy the dynamic as a deep dive into characters and roles, I'm not going to shame you.
At the end of the day we're all here for the drama, the rom-com adjacent, bloody, messy, loving, hating, fucked up vampires and we should leave each other alone.
*Big disclaimer. Fiction does not mean you can do whatever you please and it's excused by being fiction, by which I mean those who defend.. more than questionable representations of children in fiction and use said "but it isn't real! they're fictional!" as an excuse. That is not what this means.
