Is Keffals doing that though? I don't see the context to support that claim. If Keffals was responding to an original post about Palestinian genocide, I could see it, but a statement on its own may or may not being doing whataboutism. There isn't enough context to determine what's going on here.
I dug through Keffals' Twitter and this is part of a rant about how she's justified for going after "tankies" while the Palestine situation happens. She didn't make a thread so maybe it genuinely wasn't her intention but it looks like she started raging about Second Thought's takes on Israel, then started raging about people who don't want to vote Dem in the general elections because of the recent events. On Palestine itself she seems to be playing "Both sides bad".
