I don't disagree with the sentiment of your post, but I don't think that is the point the previous poster was making. It's naive to think other people won't make judgments about your choices. Even more so if you think that those judgments can't affect you. I assume you maintain decent personal hygiene/comb your hair/wear appropriate clothing? Why?

The reality is that the community around you can and _does_ produce effects material to your life, even if you aren't aware of them. Maybe you weren't invited to that BBQ? Maybe you then missed the opportunity to connect with someone in your field of work? Who knows...
