No, what I saw people bristling at mostly were either 1) injecting “yeah, well Biden sucks because genocide” into conversations about Trump or about the election or something in that arena, or 2) people jumping into conversations and rattling off low-effort posts with things like “Genocide Joe” namecalling or just purposeless negativity.
I haven’t seen many cases where people have pushed back on people who appeared to be trying to have honest discussions and didn’t appear to be trying to justify supporting Trump.
The general feeling has absolutely been that Biden needs to stop fucking supporting genocide (although people have also definitely tried to say how he’s doing the best he can given limited influence and all options being shitty in some way, or how he’s using the weapons shipments as bargaining chips, or whatever).
