LeBron James is sickened by the shooting death of 25-year-old black man Ahmaud Arbery ... saying African-Americans are "literally hunted EVERYDAY/EVERYTIME we step foot outside the comfort of our homes!" ... and he's demanding justice.
Back in February, Arbery was jogging when he was chased down and killed by a white man named Travis McMichael.
Graphic video of the fatal shooting surfaced online this week ... which has prompted a nationwide call for justice as McMichael has not been arrested or charged.
LeBron is joining the fight for Ahmaud .
