Not at all. We've seen this our whole lives, and are currently seeing it with the liberal response to the ongoing genocide in Palestine too. They only support emancipatory movements in theory, but in practice are the same as conservatives: they stop when those people are taking direct action for emancipation, specially when it threatens their own positions.
"...who constantly says: "I agree with you in the goal you seek, but I cannot agree with your methods of direct action"; who paternalistically believes he can set the timetable for another man's freedom; who lives by a mythical concept of time and who constantly advises the Negro to wait for a "more convenient season." - MLK
Liberals didn't like Mandela's use of force to overthrow apartheid in South Africa, and they wouldn't approve of it if it happened now either. The same way they aren't approving of Palestinian resistance groups like Hamas in their war against the apartheid colony "israel".
