The logical fallacy of condemning any opposition/criticism directed at specific people or organizations as constituting an assault against the very values said groups claim to uphold.
Typical examples:
Depicting criticism of the Church as an attack against God or Christianity
Depicting criticism of specific scientists or scientific institutions as "anti-science"
Depicting criticism of BLM as "racism" or "white suprematism"
Depicting criticism of Israel as "anti-semitism"
All arguments of this kind expose a deeply religious mindset that treats human organizations as living incarnations of abstact principles, therefore they're fundamentally indistinguishable from accusations of blasphemy.
