I've been searching for this word and found it using Chat GPT:
A word that describes a person who is hyper sensitive and vocal with their opinions is "combative."
This word means inclined to fight or argue, often in a aggressive or hostile way. Someone who is combative is very sensitive to the opinions of others and is quick to express their own opinions in a forceful or confrontational manner. They may be easily provoked and may become argumentative or aggressive when challenged.
Combative individuals may be prone to fighting or arguing over even minor issues, and they may have difficulty compromising or finding common ground with others.
