One polite request to lower the volume on a Bangkok BTS train has become one of Thailand's most discussed incidents in the past week. Much of the debate has centred on nationality, tourism and whether the foreign visitors involved should have behaved differently.
As someone who has worked in criminal justice and violence prevention, I saw something different: how an ordinary disagreement can escalate into gendered humiliation and behaviours that lie on the continuum of violence against women.
This is not only a lesson for tourists or for Thailand. It is a lesson for all of us. The behaviours we tolerate today become the social norms we inherit tomorrow.
A Thai woman politely asked a group of foreign visitors to lower their voices on public transport.
What might have ended with a simple apology reportedly escalated into insults, obscene gestures and behaviour many viewers interpreted as racially and sexually degrading.
The incident quickly became national and international news because people were reacting not only to noise but to contempt. Unlike disagreement, contempt communicates that another person's dignity is unworthy of respect, signalling that conflict is escalating rather than being resolved.
Some readers may question whether this incident belongs in a discussion about violence against women.
I believe it does -- not because every act of disrespect is violence, but because prevention requires us to examine the behaviours and social norms that make disrespect, intimidation and humiliation acceptable. Addressing them early is one of the most effective ways to prevent more serious harm.
Researchers have long described violence against women as existing on a continuum. At one end are behaviours often dismissed as "minor": sexist jokes, public humiliation, degrading comments, intimidation and sexualised gestures. At the other are harassment, coercion and physical or sexual violence. While not every act leads to more serious abuse, these behaviours normalise unequal power and lower the threshold for harm.
In discussions about violence against women, especially in Thailand, we often focus on criminal offences after harm has occurred. Far less attention is paid to the attitudes, behaviours and social norms that allow disrespect to become normal.
A middle finger, mocking someone's appearance or a sexually suggestive gesture may not be criminal offences. Yet together they communicate a powerful message: "Your dignity does not matter."
Even without causing physical injury, such behaviours can undermine a person's sense of safety, dignity and belonging.
The World Health Organization's ecological framework reminds us that violence is shaped not only by individuals but also by relationships, communities and social norms. Preventing violence therefore means not only responding after harm occurs but also changing the everyday behaviours that make harm more likely.
Public transport is one of the few places where strangers negotiate shared norms every day. Keeping noise down, responding politely when corrected and treating others with dignity are more than good manners -- they help create spaces where everyone feels safe.
The incident also reminds us that behaviour is socially contagious. Conflict often escalates in groups, encouraged by laughter, silence or peer approval. That is why bystander intervention has become an important part of violence prevention. Preventing harm depends not only on law enforcement but also on giving friends, witnesses and communities the confidence to interrupt harmful behaviour before it escalates.
At the same time, this incident should not become an excuse for xenophobia or collective blame. The actions of a few individuals should not define an entire nationality. Respect is a universal value, not a national characteristic.
Perhaps the most important lesson from this episode is that violence prevention does not begin in courtrooms or police stations.
It begins in everyday interactions: when we respond to correction with humility instead of contempt; when peers challenge disrespect instead of laughing along; when women -- and everyone else -- can speak up without fear of humiliation; and when communities choose dignity over dominance.
If we want societies free from violence, we must build cultures in which respect, dignity and gender equality are everyday social norms because violence prevention does not begin with punishment. It begins with respect.
