Anti-pornography movement

Reasons for opposition to pornography include religious objections, feminist concerns, and claims of harmful effects, such as pornography addiction. Anti-pornography movements have allied disparate social activists in opposition to pornography, from social conservatives to harm reduction advocates. The definition of "pornography" varies between countries and movements, and many make distinctions between pornography, which they oppose, and erotica, which they consider acceptable. Sometimes opposition will deem certain forms of pornography more or less harmful, while others draw no such distinctions.

A 2013 Gallup survey reported that, of U.S. adults, 66% believe that pornography is "morally wrong" while 31% believe that it is "morally acceptable". The gender gap in pornography opposition has widened in the recent decades; women remain more opposed to pornography than men, while men's opposition has declined faster.

Most world religions have positions in opposition to pornography from a variety of rationales, including concerns about modesty, human dignity, chastity and other virtues.

Some feminists are opposed to pornography, arguing that it is an industry which exploits women and is complicit in violence against women, both in its production (where they charge that abuse and exploitation of women performing in pornography is rampant) and in its consumption (where they charge that pornography eroticizes the domination, humiliation, and coercion of women, and reinforces sexual and cultural attitudes that are complicit in rape and sexual harassment). They charge that pornography contributes to the male-centered objectification of women and thus to sexism.
