Sexual freedom has increased. 

This includes the freedom to take part in sexual activities which were previously considered unacceptable or even criminalized, such as BDSM, fetishes, child molesting and homosexuality. 

Freedom to view violent and immoral sexual material including movies, music, art, pornography and literature has increased, and censorship of these and other arts has decreased.

The power of religious groups subsides and some are being silenced, often accompanied by a rising secularism.

The most cited example is the social revolution and sexual revolution of the 1960s in Europe and America, giving rise to more liberal attitudes toward artistic freedom, homosexuality and drugs. 

Also commonly mentioned is the general loosening of Britain’s former adherence to Victorian values.
