We criminalize behaviour when it is truly harmful. Especially when it is so harmful that it leads to someone losing her life. Eye rolling and gossip are not harmful enough to be criminal offences. Nor would they be under this law. What would become a criminal offence would be the sustained and prolonged torment of another person to the point of pushing her to committing suicide, whatever forms that torment takes, whether it’s gay slurs, or physical threats and insults. It has also long been established that there are limits to the freedom of speech or expression we enjoy, if that can result in the direct harm of others. For example, we don’t allow people to incite violence against others.
