Leftists, not liberals.

How do you tell the difference between liberals and leftists? Easy. Liberals believe in freedom of speech. They might disagree with what you say but will defend to the death your right to say it.

Leftists, on the other hand, freely use censorship as a weapon of first resort. Their own positions are so weak that if people are allowed to point out the many problems, they would collapse.

The left hijacked the label liberal, something they have never been. After they ruined and destroyed the meaning they moved on to "progressive". Leftists hate liberals, just ask them. "Liberals get the bullet too" is a common catchphrase, referring to the executions they plan after their revolution succeeds.
