I’d wonder if it happens in regards to stuff involving rape, though. People get weirdly defensive of the characters being unwilling (despite being very willing in a meta sense)

It seems to only happen with vore, too.  
“Why doesn’t the unicorn just teleport out of those chains, or use telekinesis to stop the riding crop, pull out the bit, etc?” - literally no comment on a BSDM image ever

Same here. It happens almost every time.
 
“Why don’t they use their magic to escape?”  
“I don’t understand this fetish!”  
“How did they even get into that situation?”  
“How do people get off to this?”
 
This isn’t fine literature, it’s fetish fuel, fap material. If that simple fact is beyond their comprehension, I doubt trying to explain it will help any, though.

It is a fetish. There are no rules, except what gets people off. It would kill boners if they suddenly stabbed their way out of the snake, so it does not happen.

the horn is blunt, and it is a cartoon snake so it can probably take quite a bit more abuse before getting stretched too far by the horn

im sure a horn or two can pierce through, look at stories of pythons dying from gazelles’ horns, and those were dead, these two are well and alive enough to pierce through and escape

rarity proved in princess twilight sparkle that horn magic can be doused, and there is quite a bit of liquid on it, also i doubt that her horn is sharp enough to do much more than cause it a severe tummy ache, given the shape shown in this picture

You have a horn, use magic. Or better yet, stab your horn through it’s skin and tear your way out.
