The Marxists call this Repressive Tolerance.

It's a paper written by Marxist Herbert Marcuse.

"Movements from the left must be extended tolerance, even when they are violent, and movements from the right must not be extended tolerance, even to the point of censoring and pre-censoring them so that the thought that might preserve the status-quo cannot even enter the mind."
