Find the margin of error. Accelerating Acceptance 2018 was published by GLAAD with the results of surveys conducted by the Harris Poll in November 2017. The Accelerating Acceptance report is the "first-of-its-kind index to measure American attitudes toward lesbian, gay, bisexual, transgender, and queer (LGBTQ) people and issues." For the first time since its original publication four years before, GLAAD found an increase in non-LGBTQ people who were uncomfortable around their LGBTQ counterparts in certain situations. Of the 1897 randomly sampled non-LGBT adults, 31% reported they were "very" or "somewhat" uncomfortable seeing a same-sex couple holding hands.
