Calling it a party store is common in the suburbs of Detroit. In the city itself it is almost unanimously just called a liquor store. If it sells gas then you just call it a gas station.
This seems to me like a very High School English teacher inspired interpretation of the story. I'm not sure what your distinction is between opinion and thesis, but in either case the "sins of the father" quote is just a dramatic element of the story. The thesis IMO is quite clearly a critique on the hypocrisies of the Norwegian society at the time. The characters in the book that all proclaim traditional values and virtues are all hiding despicable behavior while the mother and son subscribe to a more progressive morality and are punished for it.
Also Carver might feel more vital and reel considering his stories are about people in my parents or grandparents generation (people I've met), whereas Ibsen was writing when Victorian England was still a thing. I love both authors btw.
There are many, many institutions preforming global IPv4 scans daily and many tools that allow you to do it[0][1][2]. The trick is to "Be a good citizen", work with a scan friendly host, signal your benevolence, and limit the rate at which you scan. Also smart to black-list DoD networks. If you don't believe me setup a honey pot and open up a popular udp amplification port. Haven't done so myself but I would expect many instances of scanning would be seen everyday.
