We all have different interests in life; that’s no secret. As long as each of us can keep up with our interests without pushing them too much on others or being disrespectful about the things we like, there’s no problem with that. Yet, some people tend to cross that line.
For example, the man with whom this OP went on eight dates. On their last one, he invited her to his home, which was decorated with Japanese-themed stuff. The second the woman saw it, she got freaked out as she realized that the reason the guy went out with her wasn’t her personality, but her ethnicity.
