I'm sorry, but I disagree.
I think... No, I'm sure that the so-called gaslighting is bullshit.
It's an excuse for cowards. Cowards justify their cowardice by saying that someone has suppressed their will, although in fact they understand everything perfectly well, they know that they are being deceived, but they simply lack the courage to defend their opinion, their position, their right. It is psychologically easier for them to agree with someone else's opinion, follow someone else's will and go with the flow.
They are simply afraid of conflict.
