People are comparing deportation to concentration camps.

Deportation is the legal process of removing individuals from a country, typically for violating immigration laws. It involves detaining and returning people to their country of origin or another designated place. The intent is to enforce immigration policy, though it can involve temporary detention in facilities with reported issues like overcrowding or poor conditions (e.g., U.S. ICE detained ~510,000 people in 2019). Outcomes range from relocation to, in rare cases, dangerous repatriation.
Concentration camps are facilities for the mass, forced confinement of groups, often targeting specific ethnic, political, or social populations for oppression, forced labor, or extermination. Historical examples include Nazi death camps or Japanese-American internment camps during WWII. The intent is systematic persecution or genocide, with extreme suffering or death as outcomes.
Key Differences:
Intent: Deportation enforces immigration law; concentration camps aim to oppress or eliminate groups.
Scale/Severity: Deportation involves temporary detention and removal; camps involve prolonged, inhumane confinement, often with mass casualties.
Context: Deportation is a legal-administrative action; concentration camps are tools of authoritarian or genocidal regimes.
