In the late 2000s and continuing through the 2010s, the city has seen a surge in new business, particularly from the LGBT community which constitutes a larger percentage of the population than is typical for a rural community and one of the highest in Georgia. Despite some recent reports of Blue Ridge rivaling Atlanta as the most LGBT-friendly city in Georgia, there are notable facts that challenges this notion. As of 2020, there are over 30 LGBT-centric public gathering spaces in the Atlanta area. There are none in the Blue Ridge area. In 2019, heavy opposition followed students wanting to create a Gay-Straight Alliance club at Fannin County High School. In contrast, hundreds of public high school students in the Atlanta area are active members of Gay-Straight Alliance clubs and this has been commonplace for decades. In 2018, Atlanta's mayor established the city's first LGBT Advisory Board. The Blue Ridge mayoral office never had any type of LGBT advocacy group. In the 2016 U.S. presidential election, 82% of Fannin County voted for Republican Donald J. Trump, the most anti-LGBT candidate according to GLAAD and the Human Rights Campaign. Only 27% of Fulton County voted for him in the 2016 election. In 2016, notable backlash came from the local community over Fannin County High School considering to allow transgender students utilize restrooms that match their gender identity. During a Fannin County Board of Education meeting discussing the matter, a 2012 transgender graduate of the high school stated he was often beaten and harassed by students who were strangely consumed and misinformed about his identity. Throughout the meeting, hundreds cheered on speakers who called LGBT people "perverts" and "pedophiles".
The Fannin County School District holds pre-school to grade twelve, and consists of three elementary schools, a middle school, and a high school. The district has 179 full-time teachers and more than 3,212 students.
