Surprisingly... it's more complicated. Trump, despite being blasted as "Anti Muslim" gained 35% of their vote, Biden 64%. What is more, the Democrats have been losing that vote year over year. It's on-trend to become 50/50 within a decade. The split is largely along those who are practicing Muslims, and those who are Muslims in Name Only like your Omars.
Afghans are largely going to fall in the former category, and they are unlikely to forget that this fuckup is entirely Biden's fault. The initial drops in opinion towards Biden by the general group also say that Biden may have hastened that trend.
The latter, again it is initial results so this may change as people's thoughts solidify. But initial looks say that people have soured greatly to the idea that we had an insurrection now that they got a look at a real one.
Also, basically, everyone polled has heard about this and seen something related to it. It is -way- beyond memory holing.
