I'd say referring to people as terrorists and lowlife, ridiculing them, and ostracising them would be far more damaging to people who are in denial about COVID that respect and consideration ever would be. Consider this from your perspective, suppose there is a belief that someone is trying to change your mind about, would humiliation and ridicule make you more likely to listen? Or, would someone actually having a normal conversation with you?

While I completely get the need to let out your anger, as I said in the article, each individual you come across should not be the soundboard for that frustration. If your aim is to genuinely impact someone's behaviour, you have to treat them like a person.
