He was a nazi, participating in nazi events wherr they do nazi salutes.
He was part of a group that decided to attack and assault an antifascist group.
He got killed like a little shit out of his own actions.
Anyone, and I mean ANYONE who tries to support this guy is a nazi. So it doesn't change anything for the left as nazis don't vote for them.
Also, LFI is moderate left, not far left. The "far left" stance is propaganda from Macron that did all he could to make nazis seem more moderate than people who want equality. Spreading this bullshit is basically supporting the nazis.
Lemmy is getting contaminated by this nazi swine that keeps on spreading disinformation and everyone is fine with it.
