I had no idea about the origin of the picture until people started discussing it, so actually this might result in more people being uncomfortable, not less. Consider this thought experiment: suppose that in some foreign language the word "hello," once had a horrible and offense meaning. However both sides of the past social divide had forgotten its past meaning and now it is used commonly as a greeting. Now, some well-meaning historian comes along and uses this history to convince a member of a marginalized group that every time someone says hello, they are echoing something horrible and offense. Now this person will walk around with a heavy weight of paranoia, having been "woken up" to a reality that is long past. Every time someone says "hello," they will suffer through the experience of someone who is being insulted, and worse will have to then repeatedly convince themselves that no harm was meant (this is brutal if you have ever experienced it). That sounds like a curse to me, I say things like that should stay forgotten.
