Objections to pornography have traditionally centred on its tendency to ‘deprave and corrupt’. Current opponents of pornography argue that it is degrading to both men and women, transmitting the message that women are sex objects available solely for male gratification without any form of emotional attachment.

Recent research has provided evidence suggesting that it is likely that pornography can be one of the factors that contribute to sexual violence and sex discrimination. There has been rising public concern recently about Internet pornography, especially child pornography which is illegal, and also worries about children using the Internet and accessing offensive material.

It is possible to use negative screens to avoid investing in companies involved in pornography or adult entertainment services. This could specifically relate to companies which

• publish or wholesale pornographic magazines or newspapers
• distribute cut 18 certificate films or videos
• provide adult entertainment services (such as adult entertainment TV programmes or channels, table-dancing or lap-dancing, and sex shops)

It may be possible to engage with companies on this issue – for example to determine the involvement of mobile phone companies in the distribution of pornographic material.
