I don't see hypocrisy in the black response to white bigotry against them. The situation is not symmetric. Whites initiated the assault on blacks because they were black. That's racism. When blacks retaliate, it's not because their targets are white but because they are being attacked by people who are white. It's self-defense. It's analogous to a person firing a gun at another person to kill them because they hate them, and the target returning fire in self-defense. These are also not symmetric, the former being a crime of aggression, and the latter legally sanctioned self-defense. Black people are not retaliating because their enemies are white, but because they are persecutors, so not racism. If the persecutors were a diverse group, they would still be seen as enemies needing to be resisted. If they happened to all be left-handed people, lefties would be seen as the enemy and signs might go up instructing lefties on how to behave.
We see something similar in the relationship between atheists and the Christian church. Atheists have finally gotten a voice and a platform to respond to organized religion, and they're about as displeased with Christian treatment of them as blacks are of whites. Now that they've begun to fight back, they are called Christian-hating religious bigots. No, the bigot is the one who hates for no rational reason, and the one reacting to that hatred is doing so in self-defense. Also not symmetric and not hypocrisy.
This criticism comes up in one form or another in a lot of other places. Liberals are called hypocrites for advocating for tolerance while rejecting Republican opinion. This was the claim made to me recently, and I explained that perhaps this person didn't understand just what was being advocated, which is a mutually tolerant society. There is no place for the intolerant in such a society, and they should be denied inclusion among the tolerant people. There is no hypocrisy in being intolerant of the intolerant in the name of tolerance, just as there is no hypocrisy in a pacifist returning fire. Advocating peace doesn't mean that you won't go to war to defend or restore it.
Likewise with the Biden and the Democrats being called hypocrites for advocating bipartisanship, then rejecting Republican input - basically the same thing. Once again, perhaps it's not understood what was being offered, which is the opportunity to come together and work together. The Republicans will have none of it, and the Democrats are now ignoring them as the Republicans howl about Biden's campaign promise to unify, something impossible to do unilaterally, and call him a hypocrite.
The point here is that if you or I imitate the actions of others that we disapprove of, such as returning fire, it's not necessarily hypocrisy, since we're not really doing the same thing. The white supremacists are racist. Black people resisting them are not racist, even if they are forced to focus on just one race.
