A prolonged scene takes place during the Vietnam War in which fighter planes drop incinerator bombs on a jungle, weapons are fired, and several men are shown being shot at and blown up; lots of gunfire, explosions, and shouting (as well as some blood) is present. The actual fighting isn't graphic, but it's violently intense and results in the death of at least one man and in the decapitation of another man's legs; we also briefly see a bloody wound on a man's stomach and a man narrating the scene says he was shot in the buttocks (we briefly see the bullet hole on his buttock when he later shows the wound to another man). Men are later seen in a hospital, where we see men on gurneys hooked up to medical equipment and in various stages of injury, some with missing limbs; one man is briefly shown with half his face covered with a blood-stained cloth.
A woman implies she is considering suicide by getting up on a ledge on the side of a bridge, leaning over the railing, and asking if God would allow her to fly off the bridge. A man asks with concern what she means and the woman gets off the ledge. However, she seems to strongly contemplate suicide again later in the film in a scene where she stands at the top of a building, clearly high on drugs, and her foot slips, though she is able to recuperate and decides not to jump.
There's the insinuation of sexual child abuse: a young girl is said to have been "kissed and touched" by her father, who in one scene is shown chasing after his daughter when she runs through a cornfield to get away from him (we are not told whether he caught up with her or not, but we do learn that the girl was taken by the police to live elsewhere).
Bullies insult, throw rocks at, and chase another boy (one rock hits him in the head and we see a little bit of blood). Later, the boy is shown older and he is again chased by bullies in a car. He manages to escape from the bullies both times, unharmed the second time.
An African American man shouts at a white man that the goal of white people is to rape and kill African Americans and destroy their communities (this is brief, but it has strong racist overtones and may be upsetting); another racially tense scene includes a brief depiction of the 1963 "Stand in the Schoolhouse Door" incident (we hear a couple of racial slurs uttered).
Some other more violent historical events are also shown, including newsreels of George Wallace getting shot (we see some blood) and assassination attempts on Gerald Ford and Ronald Reagan. The assassinations of John F. Kennedy, Bobby Kennedy, and John Lennon are also referenced, but not shown.
Several fistfights occur throughout the movie that result in bloody noses, black eyes, and other minor injuries. One such fight ensues from a man's violent reaction to a woman getting slapped across the face and knocked to the ground.
People make mocking references to a man's low intelligence throughout the film and he is made fun of for it several times, often behind his back or without him fully understanding what they're talking about.
A woman calls a man "stupid" and another man shouts at her to not call him that and throws her onto a bed (not too violently).
A powerful storm thrashes a large boat on a lake and we later see a news report that it was a hurricane. Some intense damage to boats, docks, and part of a town is shown (though it's not clear whether people were hurt or not).
Milder violence includes a woman approaching the house she grew up in and angrily throwing rocks and her shoes at it, breaking a window; a man running through a pile of dog feces (not shown); people making fun of a young boy for wearing braces on his legs; a boat crashing into a dock (no one is hurt); and a brief car accident.
