"WTF?" is right. A lot of those are not 'confessions', they're just things that poster interprets as some sort of doublespeak.
These would be examples of confession through accusation:
Accusation: "The McCloskeys tampered with evidence!"
Confession: "We tampered with evidence."
Accusation: "Linguistics are just power games."
Confession: "We are manipulating language as a means of gaining power."
Accusation: "Republicans will stop supporting gun rights when blacks arm themselves."
Confession: "We are disarming blacks."
Accusation: "The Rittenhouse verdict sets a dangerous precedent!"
Confession: "We were trying to set a precedent by prosecuting him."
