Yeah. Leather guy says that he could be singing Italian Opera as if that would be equivalent and obviously okay. But it obviously isn't okay if it's obscenely loud (no matter what is creating the noise), and it also isn't equivalent by leather guy's own reasoning about confusing the young child, etc.
I generally think people are way too squeamish about sex related things. But in this particular case I think leather guy is being rude, selfish and insensitive. His leather sex is not more important than his neighbour's health and comfort. I have bad dust mite allergies and I can totally understand the guy's need to remove carpeting, etc.
