I don't think you can dismiss mainstream fragrances as low quality. Also, there are a lot, if not more, of niche scents that are "extreme" and thus more likely to be disliked - the sin of the mall scents is rather the opposite - they tend to be too bland. Nor do I think that giving a fragrance ignoramus a sniff of a niche fragrance will suddenly open up his/her mind to the endless possibilities of the fragrance world.
One reason I think people associate perfume with nausea and headache is because a lot of people overapply. I hate standing in a crammed subway car with some "assertive" character poisoning the air with heavy cologne. Of course you feel sick. If you want to promote cologne, I think you better off using it wisely instead of raving about some obscure house. Thus I disagree with the title of this thread - narcissism in a nutshell and a damn pain for everyone when manifested with an overdose of cologne.
Also, some people are simply not interested in fragrances or architecture or whatever. Perhaps they are into cars or stamps or whatever instead. We all have different hobbies and interests.
