but student terrorist movements were largely left behind in the 70s

The left has never left the use of force in the past - it is as available to us today, and as thoroughly justified, as it was in the 70’s… 1570s, 1870s or 2070s.

The willingness to use force doesn’t distinguish between a left and a (supposed) “far left” - the left is not a mirror of the right, and there is no leftist equivalent to a far right (which is purely distinguished by it’s proximity to, willingness to control and/or operate the state machinery of violence).

It’s not about spots on a silly “political compass” infographic and never has been.
