I find that I tend to be much less into catfights from different cultures. I am a white American. To me, the ideal catfight is between two white American girls and I very much prefer this.
Why? I would say it's because it's easier to imagine and create a narrative that plays off of what you are witnessing when you are familiar with the culture of the participants. For example, "shame" is a big part of the turn-on for a lot of people who like domination catfights. Different cultures understand shame differently. Furthermore, when you witness a catfight, you get a general impression of the participants, and you can sort of imagine the type of people they are. Or that they remind you of another woman you know. These are just some examples. But just in general, your fantasies have much more to play off of when you are intimately familiar with the culture of the participants.
