To be clear, it's not bad to like being called dude, or to be okay with people using it for you. Your preferences are your preferences. What is bad is you yourself using it in a gender neutral way to refer to people who are not dudes.
I, for example, am not gender fluid. I spend 100% of my time identifying as a woman. There is no situation in which I would not object to being called dude, and an insistence that it's actually okay to call me dude (a masculine gendered word) because it's supposedly gender neutral, is incredibly frustrating.
