Wikipedia entry:
^"'Bigotry' is the state of mind of a "bigot", a person obstinately or intolerantly devoted to his or her own opinions and prejudices; especially : one who regards or treats the members of a group (as a racial or ethnic group) with hatred and intolerance".[1] Bigotry may be based on real or perceived characteristics, including age, disability, dissension from popular opinions, economic status, ethnicity, gender identity, language, nationality, personal habits, political alignment, race, region, religious or spiritual belief, sex, or sexual orientation. Bigotry is sometimes developed into an ideology or world view. The word is used with caution due to the inherent reflexivity.
Oliver Wendell Holmes, Sr. described bigotry in the following quotation: "The mind of a bigot is like the pupil of the eye; the more light you pour upon it, the more it will contract."[2]^

No mention of violence there either.
Since those are online resources which don't require the possession of Jabed's copy of the OED to check I think they are more appropriate to this discussion. Particularly since the online Oxford dictionary also doesn't mention violence:
