<human>: Provide a brief overview of the text.

This is the second time we've had this discussion, but this time it was more heated and more of an argument. 

My girlfriend is upset that I've told her that I would (hypothetically) be willing to date a woman with pink hair, a partially shaved head, or a nose ring. My position is that as long as someone is good looking with their hair/piercings and I like their personality, there would be no obstacle.

My girlfriend is upset because she doesn't like these fashion choices and believes that I have low standards, so she doesn't feel attractive--she worries that she isn't attractive and I only tell her she's beautiful because I could like a girl with pink hair so I have low standards.

Note: the problem is not with the hypothetical discussion of dating. That was just a framework for exploring the problem, one which she initiated ("So would you date a girl with pink hair?")
<bot>: What do I tell my girlfriend to convince her that I really do find her beautiful and I don't have low standards? Iam stumped.
