Depends on their personal experience. While there may be less discrimination based upon their sexuality or perceived gender, some people in major cities may still find that they experience a great deal of homophobia etc. Being a gay kid going to high school in Boston may be easier than being one in Alabama, but it's probably going to make their life more difficult than if they were straight. It's kind of like the situation that exists with some of the well-off URM students out there. Sure, they may not have the economic difficulties typically associated with URM status, but they still have to deal with the stereotypes, the hiring practices, the police bias, and the media portrayals of members of their group every day of their life. So while they might be better off than a first generation Mexican immigrant that's scraping by in the inner city, they still have substantially more barriers to deal with than a lot of the white and Asian kids they went to school with.
