As thousands gathered in Orlando, Florida, on Saturday to mourn the death of Christopher Andrew Leinonen, who was killed last weekend during the worst mass shooting in modern history, a handful of protesters from Westboro Baptist Church were among them. But their incendiary, anti-gay signs were met by counter-protesters who've made a tradition of blocking them out with a powerful symbol: angel wings.The tactic dates to 1999, when Westboro picketed the trials of the men charged with the horrific murder of Matthew Shepard.
