We need to redefine strength in men, not as the power over other people, but as forces for justice.

Many young men in the 1960s and 1970s came to reject some of the traditional ideas about manhood that many of their fathers tried to pass down - like unquestioning respect for authority even when that might mean killing and dying for questionable or unjust causes such as the Vietnam War.

Typical news accounts and commentaries about school shootings and rampage killings rarely mention gender.

Media play a powerful role in establishing and perpetuating social norms.

The argument that 'boys will be boys' actually carries the profoundly anti-male implication that we should expect bad behavior from boys and men. The assumption is that they are somehow not capable of acting appropriately, or treating girls and women with respect.

We need more men with the guts, with the courage, with the strength, with the moral integrity to break our complicit silence and challenge each other and stand with women and not against them.

Elite athletes learn entitlement. They believe they are entitled to have women serve their needs. It's part of being a man. It's the cultural construction of masculinity.
