I think "woman: laughing" is actually a pretty effective attack. Misogyny.
Explaining why it works is difficult but it also worked very well to attack Hillary via her laugh as well. Look at anything about Hillary and it's all "evil woman laughing". They'll do the same thing with Kamala.
Before anyone says it's not misogyny, you never see "Man: laughing" as an attack. There is a reason it only happens to women.
On the other hand, Kamala doesn't give the same "evil" vibes that Hillary. To be sure, she sold her soul to the machine, but to me it just seems like she's nervous all the time instead of a machiavellian lizard robot
They both appeal to wine moms/aunts but Kamala's wine mom/aunt energy always came across a lot more genuine to me. When I watched that compilation of her laughing from the screenshot, it always seemed like sincere joy lol.
