One could say the same thing about the Congresswoman from Idaho who voted AGAINST declaring war on Japan in 1941.
Yes, the intent of these people needs to be considered imo.
Regarding Section 3 of 14th Amendment (14A), my main concerns about Rep. Omar is not only her asking the judge for compassion for the men who had planned to join ISIS, but also the note in this thread about her support for al-Qaida.
Both ISIS and al-Qaida arguably have “representative" in Congress with Rep. Omar. And I think that it was the intent of the drafters of Section 3 of 14A to prevent situations like this.
