A successful gay businessman has criticised a university report suggesting a slowdown in tolerance of homosexuality among ethnic minorities, saying it was “offensive” to claim tolerance was on the decline. The analysis by the University of Manchester suggested that people who were black, south Asian or religious were still far more likely to think homosexuality was wrong. Based on a National Survey of Sexual Attitudes and Lifestyles in 2010 it said a person’s religion and ethnicity was now more strongly associated with their attitude towards homosexuality than their level of education. But it also concluded that British society may be reaching “peak acceptance”. The statistics showed that in 2010, 58 percent of black and south Asian 16- to 44-year-olds believed same-sex relationships were always wrong – down from 67 percent in 1990. That compared with just 12 percent among white respondents in the same age group (down from 46 percent 20 years earlier).
