I think that Chris's relative calm in the face of trolling comes from either finally coming to understand that he can't get rid of them, or from a genuine victim's acceptance that he will be insulted, harassed, or goaded by the trolls into doing something, but cannot do anything about them, thus tries to deal with them by simply sidestepping them. This frustrates the goobers who are trying to get him to make a spectacle out of himself, but then, we use the word 'ween' for a reason. Chris's biggest hits normally come out unbidden, generated entirely from the man himself, free of outside influence.
Like
@Pickle Inspector mentioned, Chris really reacts poorly when he doesn't get what he wants. You have to remember that the thing Chris wants more than anything in all the world is
agency. He doesn't have control of his life, and has never had any romantic potential, so he wants a woman/some women to come an provide those for him. He doesn't have any friends, so he pretends that his cartoon characters are real so that he can talk to them, control the conversation, and have concerned associates who agree with and encourage him. He has no power over society, either as a whole or to the person, nor any significant control of his physical self, so he invents magic - sometimes on the spot - to deal with the fact that no, nobody's going to stop his trolls, no, nobody's going to spread the message of his Sweetheart Search, and no, his mom hates his pretending to be a girl shtick, and can cut his hair whenever she feels (lack of agency again), so no, his hair isn't going to grow back any quicker. It could be that his LGBT tolerance show is another way of deflecting the fact that the trolls have essentially beaten him.
Chris seems to have realized quite some time ago that he himself will never have the agency he wants, so he invests in his magical thinking, TV-based platitudes, and sense of entitlement in order to believe that that agency will come to him. But when reality comes and shatters that investment,
that's when he goes nuts. I'm not advocating trolling or establishing a trolling method here, but any troll who wants to see Chris go bonkers (either in a rage or while simply being himself) need not try to provoke a response. All they have to do is get Chris's attention and let him believe as he wants. That's when the true Jenkins Jinkies is revealed.
