Culture / social environment can have a big impact ( not always ) on our way of seeing things, indeed. For me it's an evidence. I'm taking a few irl examples. I know a bulgarian girl, she never saw once a black guy before coming to live in France, not even other dark skin people. I remember how she she kept looking at me the first time we met. She was fascinated and I couldn't believe myself what she told me. She didn't even see black people on TV or in magazines in her native country.
It was a bit unflattering, but I am pretty sure that what she thought about me, was well, he " looks weird " the first time, given her facial expressions.
So I doubt that she'd ever dream about anything else than what she has only known her whole life. So the white caucasian, blonde or with dark hair, etc etc. I think she doesn't find attractive anything else to her than white caucasian ( indian, muslim, black, asian don't attract her ) That girl likes video games and she certainly never would create a black character in any of them, whether male or female. And it is totally okay for me, because it's not for anyone else to decide what can play, I'm also aware that social environment can really influence the point of view of someone, or maybe not sometime and it is just the way it is ( to each its tastes anyway ), and I don't particularly care in this case to be honest. Everyone is allowed to like whatever the hell they want.
On the opposite I have for example four white female friends of mine and they only date black guys since high school. Why, I don't know, don't ask me, I have no idea and they don't know themself. But they find them very attractive, while they are not particularly interested by other types. What changed ? They didn't think that way before high school. I'd say that culture and social environment might have happened again. Many of their friends are black whether female or male since high school too, those girls for example learned things that they didn't know before, learning for example how to dance black music that they enjoy, [ and today they dance as well as their black friends what they didn't know before but learned with time and experience. You'd almost think it was in their blood ] whether kizomba, zouk, etc, so I suppose it might have affected they way of seeing things. Or maybe not, who knows ? But I guess something happened. You just don't only date one type just like that.
Otherwise, funny note, but that I find interesting since we are talking about culture differences : I came in Spain for the holidays with my girfriend ( now ex- but whatever ) a few years ago, and plenty of people were looking at us weirdly, plenty of times. I hold her hand or kiss her on the streets, and suddenly white people looked at us ( mostly old people or folks who had more than 30 years old ), almost fascinated. It was obviousy very bizarre for them. My spanish friend who welcomed us in his house for two months for the holidays then explained me the reason : I was black, she was white. In spain, mix couples hardly exist apparently, there are very few black people, and under the dictator Franco, they apparently didn't exist at all. ( I have no idea if it's true or not, but the weird reactions around us many times made me believe it was in part true ) unlike France where it is just a normal thing that happens a lot nowadays. Though in Barcelona, it felt like home, but at the same time in Barcelona, there are also many french folks. You hear so many times people speaking french around you that you'd think they invaded Barcelona. After " catalan " and english, " french is the third language certainly because of that lol.
On the opposite, when my spanish friend came to live in my home in France for six months, this time, it's him who was astonished, he never saw so many mix couples, whether in college, high schools, on the streets, whether adolescents or adults, and where it is considered " normal. " Nobody will look weirdly at you on the streets. That's where I came to realize that actually few white dominant countries had probably many black people, and that that kind of things wasn't as " normal " as I might have thought before.
Another example, my sister because of school came in Japan to live over there one year, studying in a japanese school, and she told me that she was treated like a celebrity over there since he first day. Without even asking her opinion, ( what she disliked ) plenty of times japanese folks took shots of her with their phone. And she was treated as well as a curiosity by many japanese folks, especially by children who were like " ooh look mum ". So obviously, for many of them, I'm pretty sure it would never came to the minds of young people over there the idea to create black characters for them in a video game, but either white or asian. It has just nothing with racism, or bad stereostype.
All those funny life experiences, just to claim that culture differences is a real and big thing, and that we shouldn't blame anyone for liking or dlisking something over tastes, for playing only one thing and not the others. If a male never play female characters, he is not sexist, if a white guy doesn't create anything than white characters, he isn't racist, just because a straight guy doesn't play gay characters, he isn't homophobe. We have just our culture differences, our point of view, our own life experience that can affect us and can design how we see things. Some people like new things, can adapt, others migt just play with what they identify with or what they always have seen in their social environment and what they can relate to, etc.
