So is "cancelling" primarily a leftist behavior?(dixie chick, freedom fries...)
I'd say its done in a louder way. Cancelling often comes from a moral perspective that a person or organisation is acting in an unequal, unfair way. The left are more socially conscious (again not always). The big attempts to cancel seem to be related to gender, race, sexuality related issues (JK Rowling is a prime example) and the right wingers tend to boycott in response to 'woke' organisations (e.g. Sainsburys in the UK making safer spaces for black employees).
The right generally doesnt seem to boycott because a company marginalises minorities, exploits workers etc. At times they do but if question whether they are more centrist in that regard.
Again there is no definite truth here. We can't make sweeping generalisations aand I am only pointing out my personal observations. I have no dog in the fight. I don't identify politically because it's a fundamentally flawed system of thinking. I view each idea on its own merits and ALWAYS assume I am missing info.
