The one thing that I do with intense feelers or immature feelers, is to start arguments with them as little as possible. I can't stand trying to argue against somebody's morals with logic, it never works and just ends up pissing me off. Usually it consists of them talking over me by yelling random arguments that make no sense, while I stand there annoyed.
A recent conversation with my ESFP sister:
Me: [stubbed my toe] Goddammit!
Her: You shouldn't say that...
Me: Why not?
Her: Because you just shouldn't.
Me: You haven't given me a reason.
Her: Just don't. You don't know what will happen.
Me: What do you mean "what will happen?" Do you mean to say that something bad will happen to me if I say it? That God will punish me?
Her: I'm just saying that you don't know in what ways God may be protecting you. So don't say it.
Me: So God will punish me by ceasing to protect me if I say "goddammit?"
Her: No, not punishing, just removing protection. God doesn't punish people like that.
Me: But that *is* a form of punishment. Do not parents often punish their children by removing their privileges?
Her: I know what you're doing. You just want to be rebellious. What have you ever suffered at the hands of Christians to make you so bitter?
Me: Huh? What does that have to do with the conversation?
Her: Because you just think that you're so smart and that you know everything. You don't know everything, so you shouldn't take risks by taking His name in vain. You're just being a pseudo-intellectual.
Me:

I quit.
Her: That's because you have no point [insert exasperated half-laugh].
I don't think that this is necessarily typical of all Feelers, but it's what annoys me most about the ones that I've encountered. Also the constant vigilance that you need to practice in order not to hurt their feelings is annoying. Even with the healthy ones, their powers of interpretation tend to work on overdrive when it comes to discerning whether or not something said or done was meant as a personal insult.
