I ship Stevidot romantically & I don’t see what the problem is.
There are similar ships like Dib x Zim & Finn x Princess Bubblegum. Both of
them have minors in a romantic relationship with someone much
older, but neither of those get nearly as much hate.
“I find it weird how people kept claiming Invader Zim was too weird and ‘scary’ for kids which caused it to get canceled. While, Courage the Cowardly Dog on Cartoon Network had the same level of weirdness and was even scarier than Invader Zim. Yet, no one complained at all! Seriously, sometimes CTCD gave me nightmares!”
