Fan-related pet peeves:
1. Complaints that skater(s) X's PCS was too high because the program "had no transitions". Transitions are one component, not all five.
2. Fans who form their opinion regarding a program and a skater without actually watching the program or the skater: e.g., complaints about Plushenko flailing and posing whether he does or doesn't; about Kostner winning with "80s jump content" when she does all her jumps but the lutz (one would think she is the only skater to leave out one jump) or about her winning with "messy skates" when she skates fairly well; claims that Joubert gets marks for hip thrusts when his programs had/have no hip thrusts; "Kozuka doesn't bother to connect with the audience/always looks down"; etc.
3. The use of "it made me cry" as a criterion in the evaluation of a program's merit (full disclosure: no program has ever made me cry).
4. The use of the word fact to denote an opinion (especially loathsome when the phrase "the fact of the matter" is used, which my English teacher warned us to never, ever do).
5. Hyperbole and excessive use of punctuation in forum posts.
6. "My favorites deserve to win, everyone else is politikked". Option 2: "my favorites deserve to win, other skaters get good marks because they're good looking" (also known as The Korpi Theory).
7. Comparing scores between events, especially between national events, which aren't overscored to the same degree in all countries.
8. Bringing up the same skater(s) over and over, regardless of whether they have any relation to the topic of discussion or not (exemption: Michelle Kwan).
9. Confusing criticism with hate.
10. People who suggest that pairs and dance teams who have a romantic or passionate connection on the ice are better (I love Out of Africa, but I'd rather see S/S explore other styles than repeat it).
11. Comments about skaters' weight. Actually that's not a pet peeve; it is just wrong.
