"Here's the thing, I don't care if you're convinced.
If you want me to care about you being hurt you have to convince me that you're being reasonable. And if you don't I don't care if you're hurt, and I won't care to convince you that you shouldn't be hurt."
I guess this reflects a fundamental values difference, which is why I'm replying on my blog and not directly to the commenter.
If someone says they feel hurt, I'm going to believe them. They don't need to convince me. That's because as a general rule, I don't want to hurt people. It's important to me to not hurt people. That's more important to me than logic or being right.
So, if someone says "hey, it hurts me when you do that thing", I'm going to stop doing that thing -- assuming, that is, that I don't have a compelling interest in doing that thing. So if "that thing" is breathing, yeah, I'm not going to stop doing it. On the other hand, if "that thing" is using a word that I could easily find alternatives for, then sure, I'll stop using it! Even if I think they're being unreasonable, even if I don't understand why it hurts the person. The important thing is that they're being vulnerable by telling me it hurts (there's no reason for them to lie about it), so why should I keep hurting someone for no good reason?
Here's another example that I've used before. Suppose you are a person who has testicles. If I feel like giving you a swift kick to the crotch, does you have to convince me that it would actually be painful for you if I did that? After all, since my testicles are silicone implants, it doesn't hurt (especially) for someone to kick me in the junk. So why should I believe you when you tell me it hurts for you? If I think you're being unreasonable, does that give me the right to kick you in the junk? (The answer isn't "no, because it's illegal", since that doesn't give us any insight into why it is.)
So if I call you "hypersensitive" because a kick in the crotch hurts you more than it hurts me, when that's really because you were born with testes and I wasn't, what does that really mean? Likewise, if you call me "hypersensitive" and say I need to "grow a thick skin" because I've had experiences that you haven't, and thus am hurt by things that don't hurt you, what does that really mean? Is it different from me telling you that you should "grow a thick skin" by getting your balls removed so that I can kick you more easily?
