Celebs were lining up at the Grammys to speak out against ICE ... but Jelly Roll wanted no part of it, flat-out dodging the topic and calling himself a "dumb redneck" when asked for his take. Fresh off winning 3 Grammys Sunday, Jelly was pressed backstage about what’s going on in the country RN, but he shut it down fast ... saying nobody should care about his opinion, especially since he hasn’t been keeping up with the news and didn’t even have a phone for 18 months at one point recently.
