First, address the member in a calm and friendly manner, reminding them of the happiness.com Community Guidelines and that the chat is meant as a safe space where everyone is accepted and heard, but civilly and respectfully at all times, even when you're angry and frustrated.
If the behaviour persists, or there's already a severe instance of insult/harassment, or you feel uncomfortable intervening, that's OK. Please report the inappropriate or disruptive behaviour to a Chat Op or Chat Admin. You can do so anonymously by hovering your mouse over their chat message and clicking on the triangle that appears next to it.
By reporting a member, the Support Team will get a complete history of the chat and will look into it for you.
The only time we can no longer be tolerant is when it comes to intolerance!
