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.
