The left is inciting violence, and they accuse others of the same because they project their behavior onto everyone else.
The left has stumbled onto an ingenious way of shutting up their opponents or at a minimum discrediting and marginalizing them: label any thing that disagrees with your position as hate speech, incitement or incivility.
Your opponents then have no legitimacy and everything they say can be dismissed, even if it makes perfect sense. One necessary ingredient to this formula: a complicit media structure where no contrary views are allowed.
