Masculinity (also called manhood or manliness) is a set of attributes, behaviors, and roles associated with men and boys. Masculinity can be theoretically understood as socially constructed, and there is also evidence that some behaviors considered masculine are influenced by both cultural factors and biological factors. To what extent masculinity is biologically or socially influenced is subject to debate. It is distinct from the definition of the biological male sex, as anyone can exhibit masculine traits.
In gender studies, hegemonic masculinity is part of R. W. Connell's gender order theory, which recognizes multiple masculinities that vary across time, society, culture, and the individual. Hegemonic masculinity is defined as a practice that legitimizes men's dominant position in society and justifies the subordination of the common male population and women, and other marginalized ways of being a man. Conceptually, hegemonic masculinity proposes to explain how and why men maintain dominant social roles over women, and other gender identities, which are perceived as "feminine" in a given society.
The concept of toxic masculinity is used in media discussions to refer to those aspects of hegemonic masculinity that are socially destructive, such as misogyny, bullying and violent domination. These traits are considered "toxic" due in part to their promotion of violence, including sexual assault and domestic violence. Socialization of boys also normalizes violence. Self-reliance and emotional repression are correlated with increased psychological problems in men such as depression, increased stress, and substance use disorders.
Social norms are shared standards of acceptable behavior by groups. Social norms can both be informal understandings that govern the behavior of members of a society, as well as be codified into rules and laws. Social normative influences or social norms, are deemed to be powerful drivers of human behavioural changes and well organized and incorporated by major theories which explain human behaviour. Institutions are composed of multiple norms.
The men's liberation movement is a social movement critical of the restraints which society imposes on men. Men's liberation activists are generally sympathetic to feminist standpoints. The men's liberation movement is not to be confused with different movements such as the men's rights movement in which some argue that modern feminism has gone too far and additional attention should be placed on men's rights.
