Feeling their notches.
For decent church-going women,
With their mean, pinched, bitter,
Evil faces.
Thanks for "Kill a Queer for
Christ" stickers.
Thanks for laboratory AIDS.
Thanks for Prohibition and the
War against drugs.
Thanks for a country where
Nobody's allowed to mind their
own business.
Thanks for a nation of finks.
Yes, thanks for all the
Memories-- all right let's see
Your arms!
Here Burroughs could mean one of two things, since fink has multiple meanings (although please note both of these meanings are sarcastic). 
 “Thanks for a nation of complete douchebags” 
 OR 
 “Thanks for a nation of snitches” 
 As Burroughs was an avid recreational drug user well into his 80s, he may be leaning towards the latter meaning (although snitches and douchebags are the same to a junkie). However, Burroughs was also a man to point out what was wrong with society, so the former is still a possibility.
