Question:
Dislike maybe is too strong, but in general, I like gourmand scents less than other scents.

Answer:
I don't dislike gourmands, but I cannot wear them because they make me hungry.
Other than that, I'm a scent-whore, too. Aldehydes, chypres, Si! Si! Si!
I thought I disliked some notes, but after joining Basenotes and getting more exposure, I find that I like everything in the right context.
Mind you, I wouldn't buy everything, but I use and enjoy every sample I receive--even if I don't like them enough to buy them.

Answer:
I don't really dislike any particular family, but generally speaking, I am more attracted to deeper, complex, multi-faceted scents. I find that most citrus scents are not like that, and also not all florals. Most of the perfumes that I love fall under the Chypre or Oriental category. There are a few florientals and a few florals, and a few very rare citrus scents that get me excited and are in my list of favourites.
But I don't negate a whole family of scents, just as I don't do that with specific notes. i.e.: even though I don't like marine notes, generally speaking, I do like how they are used in Le Parfum de Therese, En Passant and l'Eau d'Issey parfum.
I try to keep an open mind. And as time goes by and I learn more about perfumes and perfumery, it seems like it gets more and more open...

Answer:
I guess for me it's not really a whole family either, but I like gourmands the least, and anything that has that heavy, syrupy, cloying sweetness like the Frangippani or Queen of the Nile flower. It's off to the bathroom for some hot water and soap!

Answer:
I can't give a particular family, I just know I don't like extremely flowery, powdery, or sugary sweet. Like I've said on another post, I especially don't like a rose scent, wish I did. That note is in alot of nice perfumes. I don't like fruity too much, but I can handle that better than the above mentioned.

Answer:
I don't think I'd rule out a single genre, because there's such variation within each one. I do quite like gourmands, for example, but can't wear Angel. I'm still looking for an ambery/musk that works on me - although thinking about it l'Instant and Tolu are both pretty gorgeous and I think they have amber. I like florals, and aldehydes, and orientals, and used to love Clinique AE. Didn't think I liked many citrus-y scents, but Hermes E de M was yummy, and I was very taken by the Malle Bigarade this week.

I think it's like one of my friends said about chocolate - really she prefers Cadbury to Galaxy but at the end of the day it's still all chocolate

Answer:
No family that I object to a priori, but chocolate does NOT smell good to me at all - in perfume, that is.

Answer:
Whilst there are certain notes I dislike quite intensely (violet, certain musks), the only family I really detest is marine/aquatics.

Answer:
Anything with cucumber

Answer:
Three months later and I still haven't found anything to dislike. Not-prefer-as-much, maybe - but nothing I can't wear. One of the many advantages of old-er age. When I was younger and "where the whores moaned, there moaned I" (to crib from A. Huxley) many 'fumes screeched and p--ed all over me. Today my more mature body and drier skin have tamed them into the beauties they can be. Ma Griffe and Bal a Versailles come to mind.
So whereas "Scent whore" doesn't quite describe me (I don't get paid to wear them!!) ..."indiscriminate" still does!
