"Religion in my opinion is the most devisive thing in humanity. But hatred or acceptance is a learned thing." - 100% agree.+Ryan Barlow
The following comment to the one you mentioned showed how that Independent article differs significantly to the 2011 Census, so I wouldn't put too much faith in the IHS stats. Also, please learn to use Google :)
"Estimates of the occurrence of same-sex behavior range from 2 to 10 percent of the population. A 1992 study reported that 6.1% of males in Britain have had a homosexual experience, while in France the number was reported at 4.1%. In New Zealand, a 2006 study suggested that 20% of the population anonymously reported some homosexual feelings with few of them identifying as homosexual. Percentage of persons identifying as homosexual was 2–3%. According to a 2008 poll, 13% of Britons have had some form of same-sex sexual contact while only 6% of Britons identify themselves as either homosexual or bisexual. Contrastingly, a survey by the UK Office for National Statistics (ONS) in 2010 found that 1.5% of Britons identified themselves as gay or bisexual, and the ONS suggests that this is in line with other surveys showing the number between 0.3% and 3%"
Values from 1% - 20%. I was stating a mid-range value. The comment about individuals being unwilling to admit their sexuality in an environment where it's not accepted is perfectly reasonable and rational. Far from nonsense.
