Hating being devalued or attacked isn't a defect from a personality disorder. Nobody likes that. Nobody likes being abandoned either. Everyone feels sick from it. You are viewing yourself too much through this label and what a FEW of the total people you have interacted with say about that label. You are using that label to turn your suffering inward because your mind thinks that's the one victim who cannot fight back...but it DOES fight back against itself with bad emotion/physical pain/anxiety etc.
i use the label because it's easier than saying a small inconvenience triggers bad impulses, for some it triggers suicidal tendencies. it's a popular thing for bpd's to "wear their illness like a badge", and validation is a huge part of it, i'm not saying all bpd's but me especially i get really upset when one person doesn't like me. i obsess over it even if i don't know that person. others express this other ways, they gain validation by posting half naked photos of themselves online. with the feeling of being attacked i can't help but get defensive. i'm not as bad as others who have this disorder but in bpd groups, you say one small wrong thing and it could start a huge shitstorm. i'm not saying give bpd's special treatment or validate them, but i'm saying the emotions they feel opposed to someone who doesn't have it in say abandonment is significantly higher. i smashed my face on a curb out of stress, anger and anxiety leaving me with two black eyes and a broken nose, just because my ex left me. not even in a bad way. don't take this as me having a go, i'm simply explaining why it's not as easy as not victimising yourself. a lot sadder when you're limited to treatments. i had to do DBT for a few years, didn't work even though it's specifically designed to treat borderlines. there's no actual meds that can treat it either, just treating the symptoms.
tl;dr yes you are correct no one likes feeling attacked, devalued or abandoned. but borderlines react much much differently to it. i get defensive because i don't like being compared to a narcissist. i hope that explains a little why i think the way i do
