No mention of LGBT people in the lyrics, but the music video has footage probably meant to evoke the BLM protests and he recorded scenes for the video in front of a courthouse with a history of race riots and lynching ( Maury County Courthouse in Columbia, TN. Mostly the lyrics of the song seem to be talking about “city crime” and conservative no-nos like flag burning and disrespecting police. There’s also a “don’t come for our guns” line.
As someone who supports reforming law enforcement and protecting free speech (ie. flag burning), I don’t see anything wrong with a song that promotes law enforcement and criticizes flag burning. Those aren’t “dog whistles” or whatever people what to dismiss/demonize them as, they’re just an expression of views I don’t entirely agree with.
The implication is very clear that they will hurt you if you burn the flag near them. I personally don't exactly support actions limiting free speech, which is exactly what he's saying they want/already do.
