It's not fashion to wear glasses indoors. It's borderline retarded. Let's move the setting, you're having dinner with someone. They are wearing sunglasses. Any reasonable person will say, 'hey can you take those fucking things off, I'm trying to talk to you'
Here is the thing: I don't. That you think I must is extremely telling however.
I just don't have trouble grappling with the concept of people who are unlike myself. It is not hard for me to conceive of people who dress unlike me for non-utilitarian reasons. That is what fashion is. Further, I don't have to subscribe to a particular fashion to recognize those fashions for what they are; fashions.
Who is really too far "nerd/asspergered" here (seriously, your comments are so steeped in irony it is absurd...)? The person who cannot comprehend that fashion is not about utility and cannot stand those who are unlike him? Or the person who calling that intolerant, fashion-ignorant, bullshit.
Fashion is about more than utility. Your particular way of dressing is not the best way of dressing; stop dreaming up pop-psych self-aggrandizing bullshit to make yourself feel superior. Not everyone who calls you on your shit participates in the fashion trends which you vilify. Grow up.
