Difference between non-Ukrainian and Ukrainian refugees is not skin but community.
The Haitian diaspora of the United States is 2 million strong. The Central American diaspora numbers 7 million. Ukrainian diaspora is a paltry 1 million, and yet, if you went to the refugee camps in Mexico or Europe, you would not find Syrians tending to Syrians or Haitians helping Haitians or Guatemalans helping Guatemalans. Contrast with the Ukrainians who flew from around the world to help in Europe, who descended on Tijuana by the hundreds. These Ukrainian nationals and ex-patriots were not all ethnic Ukrainian, they were Jews and Russians and Belorussian. Somehow they had a sense of duty to help and community that lacks at the Afghan camps and Mexican migrant camps.
The camp in Tijuana and Mexico City received government support but only after Ukrainian volunteers and churches showed up, providing food and funds and people to help. By account of the Mexican government, never has their assistance been so small as a result of all that Ukrainians from America and Mexico provided. When Mexican government offered a shelter Ukrainian Americans negotiated for clean bathrooms, wifi, and police protection which saved lives. American Ukrainians reached out to congressmen and consulate, went on TV and demanded help getting faster processing and benefits, something you rarely see from other communities, but should.
This isn’t to shame Haitians or Afghanis or Guatemalans. It is to say that demanding without working to help isn’t enough. People are treated better when you donate your time and money and care and go to where they are, come to their aid and fight for them. Life is not an entitlement. We can expect to be treated well and complain when we are not, but this also demands action. When Ukrainians arrived in Mexico there was no one to help them. They slept on the street and were as invisible to the world as all other migrants. They became visible through the care and community of the diaspora. This same can happen for all other people who are waiting their turn in the dozens of camps in Tijuana, they just need their community to chose to physically and financially come to their aid. Because if you care enough to help with your time and money, so will others.
