The civilities are viewed differently in different countries. The difference comes from culture, customs, tradition, and history. In most of the cases, the civilities are questioned on the issues of politics and religion. Intolerance can be seen in a political debate or demonstration and religious debate or demonstration. Verbal attack sometimes even leads to the violence. I am not sure if the freedom of speech allows people to threaten their opponents. I don’t know if there is a measure in the degree of abusive speech that is allowed in a debate or protest.
