Strange... I'm trying to think why someone would be offended in a personal way by the use of the word. I could see someone being repulsed by the word if their mental picture for the word was a used condom. When I think of a word as offensive, it's usually because it's a slur against a particular group like "fag", "kike" or "cunt". If someone thinks that scumbag is offensive, what group do they think it offends? Low-level criminals? Guys who use condoms?
