The tag implication #53141 decapitation -> gore has been rejected.
Reason: I don't know why this isn't a thing already, but yeah having heads cut off should imply this so people don't get to see something unsettling.
Naturally there's going to be a little overlap from things that aren't gore, such as this. To correct this, I recommend using a tag such as mounted_trophy instead. Not necessarily gore, but it expresses the content far more clearly.
EDIT: The tag implication decapitation -> gore (forum #383882) has been rejected by @slyroon.
