Muslim people, trans people and people of color have experienced violence in airports for years. This has increased dramatically under the new US administration. Numerous cases are already happening of border patrol not allowing entry until logins and passwords for social media are handed over, which the EFF states is unconstitutional and requires a probable cause warrant. Every day, corporations like Google, Apple and Facebook regularly share data with law enforcement. Do not post anything on social media that you do not want to defend in court. Posting on Facebook is akin to writing a letter to the police, the FBI and the NSA.
