I answered your question to pokemonsquared in the thread, but I deleted it because I might be infracted for straying off topic. In case you didn't see it, I'll answer you here.
Well, I'm really glad to see that someone else agrees with me!
Fine, it's not like I'm against freedom of speech or anything. You can want a girl to win the league as much as you wish.
That was my main question to begin with...have people really lost so much hope that they're already planning out Ash's defeat?
I find it to be a pointless thing to wish for as well, but people have been losing hope and planning out Ash's defeat even before I joined this site lol. After Sinnoh most members of the site came to the conclusion that a banana would have a better chance of winning the league than Ash.
Also it's probably a lot of different reasons.
1- They lost hope on Ash winning the league, like you said.
2- THIS abomination of a thread was made. CyberCubed is a member who enjoys playing with people's minds and so he decided to make this thread to get people ranting over something dumb. Since that thread happened, some members get pissed whenever a female character loses and call sexism on the writers, especially the member named Ciccone.
Although we're not all like that. Most of us still do want the main character to win, including me. And I personally don't mind when they rant because it's just their opinion anyway~
