The word "violence" only recently had its definition broadened to encompass hurt feelings. There is an established legal definition for violence that makes it clear it is always physical
The term has unfortunately been redefined by the same people who want to use it to censor speech.
1) This isn't about "feelings", it's about the fact that speech _has consequences_. People get hurt both emotionally and physically because of things other people say, especially in aggregate.
2) Etymologically speaking, violence comes from "violent", which meant "having a marked or powerful effect".
3) Legally speaking, violence includes intimidation.
4) Practically speaking, arguing definitions is a total waste of time.
