This is can appreciate.
Seems a few of the culture references didn't translate due to your background. The imagery is just a representation of urban culture especially urban Texas. Arrogance/confidence in the face of authority which is the most prominent aspect of hip hop culture. Black and brown ppl are already looked down upon so what better way to respond than confidence to the point of arrogance? I know there's nothing wrong with me, and if you don't agree you can go fuck yourself. Smirking in the face of facism is something I considered incredibly brave. I know I'm better than a facist. I'll be smug as hell to them because as far as im concerned the only good facist is a dead one.
Grills, graffiti, and the script used don't automatically equate gang culture. The script itself is Cholo based. A part of Chicano subculture that doesn't mean you're automatically a gang member. There are tons of professional influencial artists who created and use this script with no gang affiliation. Equating it immediately with gang culture is like me thinking every white person who listens to punk or metal is a nazi. Or if they're into Nordic runes they're apart of the Aryan Brotherhood.
Not to be insulting but a lot of this reads like a suburb kid whose never explored black or brown culture. I could see Fox News trying to use this a propaganda that "Gang culture is running rampant inside these Anti-ICE protests so ICE is needed more than ever!" But that just shows their overall ignorance of anything not white, light, and suburbanite.
It do appreciate the positive notes on just the artistic aspects but overall this message isn't for you because you have no cultural frame of reference and that's ok. But personally I feel you should look into why this imagery ONLY has negative connotations with you.
Edit - If you're disgusted by imagery that is outside of your culture that's a bit problematic and honestly its the same kind of attitude that the ppl that support ICE share with you
