*It annoys me when people bash fans of ships. I have NOTPs, but I would never bash the fans.
*Similarly, while I have no issue with people having NOTPs, it annoys me when people never stop complaining about their existence, especially if they aren't canon.
*I don't like shipping wars.
*I find a lot of rabid anti-certain-ships worse than the rabid fans of said ship.
*I actually love Ferriswheelshipping.*pelted by tomatoes*
*I don't mind- and sometimes even like- age gap pairings as long as the younger party is 18+ (or ambiguously aged in canon so you can say that if you wish).
*My first ship was actually probably Ash x Ritchie. Also, I thought Ritchie was a girl for some reason. I still kind of like it, actually.
*It bugs me when people bash a ship for being popular. Give more attention to your obscure ships to get them to be popular, too. Also, as a fan of some weirder ships, it sort of makes me feel bad for said ships because then it looks like people only support them because they aren't popular instead of on the ships' merits.
*I don't hate slash, but for some reason, I have a much easier time getting interested in femslash pairings than slash... And I'm female. Usually I see the opposite.
*I am so thankful the Kalos games' shipping wars aren't as rabid as the Unova ones. They were so bad I actually had to step away from the shipping fandom for a while.
*I usually prefer the Lyra version of a ship to the Kris one, but for some reason, Red is the exception. I like both girls and their ships, that's just how I usually feel.
*I still don't have a Serena game OTP. DetectiveDuo is close, but we need more Looker in the inevitable third game.
*My OTPs tend to change a lot, but I think my current OTP (which even changed a day or two after I mentioned my last one) is male Morgan x Cynthia from Fire Emblem:Awakening. In terms of Pokémon, there isn't any I'm really fangirling over right now, but I have a feeling something will happen with OR/AS. My favorite two are Flag and NewRival (which is funny since I was a Hoennshipper in the original games).
*It annoys me in fandoms where you choose between a male and female character when someone who supports a ship with one bashes the opposite gender version of the same ship as rabidly as possible. I'm not saying you have to like both (there are plenty where I love one but am meh towards the other), but it's just kind of obnoxious, especially when the words "fangirl" or "self-insertion" are thrown around as an insult at the other party. It's especially infuriating when both characters have basically the same dialogue and story no matter who you choose.
I'm sure I'll have more, but that's the gist of it.
Confession: I loathe when people use the term fangirl to bash shippers of certain popular ships and accuse women of ruining their favorite franchises and accuse all fans of a particular ship of just wanting to ship themselves with <insert hot guy here>, even though many shippers of those ships genuinely like them and don't go around yelling at other pairings and the anti-shippers are sometimes even worse and fanboys can be just as terrible.
