Kinda late to the discussion, and while I usually agree with
@Marvin ’s opinions, this time I think it’s wrong to assume there’s a troll playing Rosechu behind his back, and I think all this (well... Twitter pool aside, probably) is basically Chris trolling himself.
Chris always saw his comic as masterpieces, true, but masterpieces that could be improved and made more lifelike, he hoped trough a video game or a tv series.
Then he saw "Rosechu story", and it was just like everything he always dreamed of: it’s professionally drawn, the characters motivations are well established, there’s drama, there’s action... it was just like the cartoons he loved so much, but with his own characters, even better!
So he probably took it as “canon”.
Now, bear in mind, like we saw during the Asperchu saga, to him every comic instance of Sonichu & Co. in comic form are actually his characters, either living adventures he didn’t know about or being impersonated by lookalikes (just like Sonic In Sonichu is actually Silvana disguised).
I think he took "Rosechu story" as the first instance: still his story, but with some more details.
Only afterwards he realized
@Trickie 's changes to the plot, like Rosechu being male (and thus having a penis) before she transformed. Realizing this, Chris decided to do the most rational thing to do: ask Rosechu directly!
Now, no troll is needed for this since Chris thinks he can actually talk with his creatures (Mary Lee Walsh said he started talking with them when she punished him one time) and so he did.
The real strange thing is that, when confornted with ths information, the Rosechu inside Chris' mind (maybe because it mirrors his own feel of being a female born with the wrong anatomy) actually responded that it was true, and that she had a penis.
Chris, being Chris, was obviously destroyed by this information and, in his usual passive agressive way, asked the public if they prefer to hurt him (admitting Rosechu's trans status) or Rosechu (deleting her past history and making her a girl from the start).
The fact that he cancelled everything after the option that would hurt him most won just underlines how much of a dick he can be, even towards his own creatures, that he thinks are alive.

R: Chris wasn't fed this by a troll IMHO, but was punished by following the super autistic rules he himself set on how to deal with his Roger Rabbit like alterante cartoon world.
