Oliver Kamm writes about a survey showing increased public acceptance of homosexuality:
Acts of Parliament turned out to be important in changing public attitudes. Given that Labour is shortly to lose office in a big way, it's worth noting what the Government has done to eradicate discrimination against homosexuals.I don't think it is true that Acts of Parliament have been important in changing public attitudes because the exact same trends have occurred in every other Western country in the last 30 years. The World Values Survey asks the question " Is Homosexuality justifiable" and the numbers who think it is never justified have fallen steadily in every comparable country to Great Britain over that time scale (except Italy):
So unless the same processes have occured in all countries it looks to me more as though Acts of Parliament have been as a result of changes in underlying public opinion and not vice versa.
As Disraeli said
