I don't know, where I'm from "disgusted" is a much stronger term than "offended". It's like a visceral repulsion that triggers something bordering on mild rage. I don't know how the OP intended it, but if it's as you describe, then yes, it's not too bad, but I haven't seen that term used so lightly usually.

To me disgusted and offended are unrelated. I'd personally agree that in magnitude of responses, disgusted is probably stronger, but, to me, being disgusted is about finding something to be awful, whereas being offended is like being hurt yourself. As a white guy, I am not offended if a racist guy talks about killing black people. I am disgusted, and hush the room and tell everyone to point and laugh at him.
