Juneteenth is the celebration of the end of slavery in the US. We need more holidays that celebrate freedom. Freedom isn't always comfortable or easy, but it is the precondition to the pursuit of happiness.
BTW, we've been celebrating Juneteenth here on this blog for a long time, if no more consistently than anything else we do.
