Their social power comes not from the accusation itself, but the squirming their opponent's do when accused of something that's not even wrong. When the crowd sees the accused person acting like they did something wrong, people assume they did. It's how leftists establish something normal as unacceptable, by starting out assertively to force you to agree to their frame of reference.
1: They accuse you of violating a moral norm that nobody agreed was even a moral norm. Intent doesn't matter, only perceived harm.
2: The moral frame is non-negotiable. You're not asked to explain but told you are guilty, any attempt to defend yourself is framed as further guilt.
3: You're required to confess, overexplain, and beg. Groveling is seen as a virtue and forgiveness is not guaranteed.
The answer when accused of something you actually did or believe is to say "yes, and?" like the serpent did. Not because the serpent was good, it wasn't good, but it did understand this concept of owning your intent as power as did many righteous people later in the bible. Including Jesus.
