Perhaps they have heard one or two CDs with "Best of Classics" which generally should be titled "Worst of Classics". Good classical music is hard to find. But in the times of youtube, the case gets better (hopefully).
Taking into accout the definitions proposed in the post of a couple of minutes ago, my feelings might be academic to the discussion anyway, as all the music I listen to and play is most decidedly very A.R.M and H.I.M.
