Aluminum Christmas Trees: The woman in this story wants to sue her ex-husband's mistress for "alienation of affection", a term which the OP has never heard. As the comments section points out, it isan actual legal term which is still recognized in some jurisdictions, including six US states... however, none of those are Louisiana, where the story takes place.
Cry for the Devil: The bully in this story, which is a stellar example of The Ending Changes Everything. While the bully in the story is a thief, vandal, and general hellion, the final few sentences reveal that he was being pressured into stealing relatively expensive items (like the submitter's bicycle) by his mother, so she could sell them for drug money. The submitter admits that while as a child, she was angry he didn't get any actual punishment (instead being rehomed with an aunt), as an adult she's more sympathetic to him and hopes his aunt was a better parent.
While no one disagrees about how much of a prick the would-be dognapper in this story is, there are also a number of comments calling out the OP for leaving their dog tied up outside unattended to begin with. Others defend the OP, claiming that it depends on the neighborhood or culture (for reference, the story takes place in Australia).
The submitter of this story seems to think that his friend's brother driving while legally blind is okay because "he had a snappy comeback" for the officer who pulled him over for speeding. The comments are pretty much unanimous in deriding the brother for endangering others just because he, as the submitter describes him, is "completely lacking in fear or common sense." Even the editors tagged the post as "Extra Stupid" and titled it "The State Of California Maybe Has A Point".note While the OP later clarified in the comments that he was being sarcastic when he said that "he had a snappy comeback", it doesn't come across as sarcasm in the story.
In this story, a pizza boy is insulted by a cranky drunk man to whom he just delivered a pizza, and afterwards discovers that the man inadvertently gave him a hundred dollar bill instead of a ten when paying him. The pizza boy then decides to pay the drunk man back for insulting him by taking the drunk man telling him to "keep the change" at the man's word, even though the drunk man turns out to be lucid enough to realize he is missing one hundred dollars and call the pizza place's manager, but the pizza boy swaps the hundred out for a ten before getting there so the manager would think the drunk man was just being a jerk. The pizza boy was ripped apart in the comments for stealing ninety dollars from a customer (even if said customer was a huge Jerkass) and lying to his manager about it.
In this story, a policeman picks up an extremely drunk student to take him back to his dorm. The student climbs in, accidentally sits on the policeman's hat (which the policeman had thrown into the back seat), and it quickly becomes clear that the student is so drunk that he has soiled himself and has now ruined the hat, prompting the policeman to kick the student out of his cruiser. Many comments criticized the policeman for kicking the student out of his cruiser when the kid was still falling-down drunk and in no condition to walk back home himself. Not helping matters is that the submitter, a fellow police officer, does not seem at all concerned about what happened to the drunk student either.
Informed Wrongness: In this story, a particularly creepy ex-teacher of the submitter hits on the submitter's mother on a dating website. The comments point out that while actions he took earlier in the story (getting too close to female students and watching explicit videos in class) were over the line, flirting with a woman his own age with no pre-established relationship whom he likely wouldn't have realized was the mother of an ex-student in and of itself is merely awkward.
