I think it depends on how you handle the situations. Being passionate about something isn't out of the ordinary. Allowing yourself to become enraged because someone else holds a different opinion is a pretty serious problem, IMO.
If you feel like you are having difficulties with relationships as a result of this, you might want to consider talking with a counselor or therapist. That's exactly the sort of thing they do - talk to you and understand what's going on, then give you practical things to work on to change your behaviors.
