melanchon has couched his disagreement with the protests in caveats that should not exist. he needs to be more forceful that these are not leftist protesters and they don't represent the left-wing; they are far right extremists and the left is getting smeared.
the problem is that while the fake left party has taken a step away from the protests, the reality is that there are a substantive number of people involved in the party, and running for it, that are not in particular disagreement. the fake left's embrace of the far right is dangerous politics. there are grounds for a strong denunciation of not just the bad actors but also the bad politics and the people responsible for it.
the left-wing eu bloc in question, which is also fake left but not as fake left as lfi, should react first by suspending the lfi as a member until it undergoes reforms to purge radical right elements from itself. melenchon should dissolve the party as toxic and unworkable and allow the left to reform outside of it for the upcoming elections.
