I blame the parent. Nobody with the resources necessary for an international vacation has any excuse for being ignorant of the current political state of the US, our government is actively targeting visibly hispanic people regardless of legality and has not been quiet about it. Even if their trip had gone smoothly every dollar they spent here would be indirectly supporting the shit our government is doing. The child had no choice in the matter, the parent was a fucking moron who volunteered their child for a completely avoidable traumatic experience and helped fund Trump's crimes in the deal.
