My wife's family won't accept me because of my ethnicity

not sure if this is the right subreddit, but I just need a place to vent.

I (34M) am Japanese and my wife (34F) is Chinese. My wife's family is originally from Nanjing and her grandparents on both sides lived through the Japanese occupation during WW2. They went through and saw a lot of horrible things and lost many people, and since then they’ve always strongly hated Japan and anything related to it. The majority of her entire family, including her parents, share the same sentiment. 

When we first got together, my wife kept our relationship a secret for a whole 2 years because she knew her family wouldn’t be happy about us. Her parents didn’t speak to her for literal MONTHS after she finally told them, and they’ve always refused to meet me. 2 months ago we had our wedding and almost none of her family members, aside for her sister and a few cousins, attended, which hurt her more than it did me. I’m sure they would probably even refuse to meet their future grandchildren because they would be half-Japanese. Even though I understand her family’s anger and resentment towards Japanese people, and I don’t blame them for it, it kills me how they direct that anger towards me. It hurts so much whenever I think about how I’ll never get the chance to know the people closest to my wife and never be truly considered part of the family. I wish they could look past my ethnicity and just give me a chance
