Hard disagree. You might be ok with loud engines splitting your eardrums and interrupting your sleep (or worse, your baby's sleep!), but society as a whole should not.
Live and let live is good and all, but GP said it was about "inflicting their taste on others," so I would read that comment to mean the inconsiderate things we should not let live. Loud pipes, unsafe driving, and loud subwoofers--I'll shake my fist at those clouds all day.
