Hmm... what about people who don't have parents? I mean, I've lost mine at a young age (my mom died when I was 9 and my dad when I was 19). :/

I do get the point of not letting the existence of relatives who may be embarrassed by your work interrupt your writing, but the actual lack of parents doesn't work for me. I do think about what anyone I know ever think about me if and when I ever publish something I wrote. I still have self doubts, so perhaps a theoretical loss of parents has one more benefit over the actual loss...
