>That would be a normal reaction if she did that, not a psychopathic behavior.
What sets her apart from the other villains is that she was the only one with empathy which is how she was able to be reasoned with. All of the others were psychopaths that needed a rainbow laser to stop/brainwash them. The only reason she was a villain in the first place was over a misunderstanding of cutie marks.
>I'm referring to her attitude when she was retaliating against Twilight
No different to Dashie when anyone doubts her abilities.
>My point is her quick switch which would make sense with the condition.
I'm guessing you are referring to her reformation. Starlight had the most believable switch out of any of the reformed villains (Discord didn't even really switch, more like he became obedient over Fluttershy, I think the psychopathic protagonist you are looking for is Discord), she retained much of her personality but was foisted into a strange new environment which put her in a very vulnerable position revealing her weaknesses. Also you have to remember that her time in Our Town was her playing the role of a strict mother figure, it wasn't entirely her true personality, and in the finale she was angry and filled with bitterness so that wasn't entirely her true personality either. The most complete Starlight in her natural state is found in s7+ after she overcomes many of her insecurities and we see her in more relaxed scenarios. But they're all a part of her in the end, all different phases of her life in different situations, they all add up to one amazing mare. Starlight is a very complex character for a kids show so I can understand how some people get confused.
>Fluttershy doesn't have social anxiety either, she talks with people just fine.
Yeah, I think you may just have a totally different definition of social anxiety and psychopathy. Clinically, Starlight is nearly the opposite of a psychopath in the spectrum because of her high level of empathy allowing her to understand others, her cartoonish impulsivity is really the only trait to match. Ponies that better fit the mental illness with the least contradictions are Twilight and Pinkie, but Discord is the best subject you are looking for.
