"How powerful was silence, but how powerful is the freedom of speech," he told the crowd via Taste of Country. The "Bottoms Up" singer also slammed social media users who appeared to be insensitive to Charlie's death. "I don't care if you're left, right, Black, white, who you wanna be today or tomorrow, whatever the f***," Gilbert, 40, shared. "You never celebrate an act of cowardice like that.
