Is this bad? Frankly, yes.
The awarding of a degree indicates that you have a well-rounded education that includes a standard regimen of required courses, courses that apply to your major, and courses that may or may not apply. That you think these are "stupid" gives an indication that you may think education is designed for your entertainment and for the goals you deermine, without any concern (or respect for the years and years of academic excellence that have decided that those classes aren't "stupid."
Tell ya what: when you go into your interview and they ask why you should be considered competitive with others who have completed bachelor's degree, I think you should tell them you didn't want to take the music or art classes because you think they're "stupid."
If you want to be REALLY popular, get someone to video the interview, and then post it so we can all get a big chuckle out of it here.
Here's a hint: Academics of any genre aren't going to take a comment about other academics being "stupid."
