No, identity isn't that cringe, as long as you treat it as descriptive and not prescriptive. You don't have to reduce yourself to labels to label yourself. Labels are just a useful shorthand for a confluence of experiences and lifestyle.

Calling all Cubans who fled from Castro, someone who made a habit of imprisoning political dissidents and came to power by violent revolution, fascists is a bit rich. You can agree with Castro's philosophy and think he did a lot of good for his country and citizens, and even argue that imprisoning dissidents was necessary in the given circumstances, without condemning those who did not want to live under his rule.

Your whole post sounds like cope to excuse being a nasty person.
