I realize you have to be living under a rock in the U.S. to not know that yesterday, was Juneteenth (a portmanteau of “June Nineteenth”). Still, I feel compelled to explain that said date marks the day when federal troops arrived in Galveston, Texas in 1865 to take control of the state and ensure that… Continue reading
