Judge Luttig: Donald Trump is not a Republican or a Conservative - Deadline - MSNBC

[Tactical Peek]

3. Luttig is guilty - of the 'No True Scotsman' fallacy.

No true Scotsman or appeal to purity is an informal fallacy in which one modifies a prior claim in response to a counterexample by asserting the counterexample is excluded by definition.[1][2][3] Rather than admitting error or providing evidence to disprove the counterexample, the original claim is changed by using a non-substantive modifier such as "true", "pure", "genuine", "authentic", "real", or other similar terms.[4][2]

Philosophy professor Bradley Dowden explains the fallacy as an "ad hoc rescue" of a refuted generalization attempt.[1] The following is a simplified rendition of the fallacy:[5]

Person A: "No Scotsman puts sugar on his porridge."
Person B: "But my uncle Angus is a Scotsman and he puts sugar on his porridge."
Person A: "But no true Scotsman puts sugar on his porridge."

The Republican Party is the national conservative party.

The Republican Party nominated Donald Trump for president three times, and elected him to office once, as a Republican.

Former president Donald Trump is today the leader of the Republican Party, a conservative Republican.

Wise up, Luttig.
