No. I think Marvel was pandering if they added it in.
The issue with not saying things out of fear of being offensive when dealing with history is that it can and does lead to a distorted view of history.
For instance when learning about World War II and the Japanese internment almost no one is taught about the Nihau Incident. the shelling of Long Beach, or the attack on Fort Stevens in Oregon.
People need to understand why thinks like both the holocaust and the Japanese internment happened and why they actually seemed like good ideas to the people of the time.
Until you understand why you might have made that same mistake at that point in history you can not learn how to avoid mistakes like in the future.
Frankly the whole Japanese internment is a sore spot for me. The way is is taught is almost always along the lines of "look at what those terrible people did to the Japanese Americans for no reason!", which is just a way of saying look how great and enlightened I am because I would never do that.
