Okay, so I general when you say, "Every accusation is a confession" it means that when a certain type of person accuses others of doing something that they are doing it themselves.

So, in the past Republicans would endlessly decry how evil homosexuality is, but they would get discovered having all kinds of gay sex.

Similarly, when the Republicans talked about Democrats being pedophiles, and then the Epstein files showed that it was actually mostly Republicans raping children.

So when the Republicans say, "the Democrats are Communists" and then your response is, "every accusation is a confession", people will naturally think that you mean that the Republicans are confessing to being communists.
