Omar is accurate in describing this as a measure to enrage Turkey first and perhaps gain favour with domestic Armenian diaspora groups. But is she not also advocating for some kind of historical crimes quid pro quo? She is implying she will not endorse any serving of symbolic recognising until her constituency's favoured, unrelated grievances are also included which waters down each of them.
I am sceptical of her sincerity given her background and the Islamic context of the Late Ottoman genocides. Recall, fellow dhimmis such as Greeks and Assyrians, were also ethnically cleansed.
I see little difference between symbolic actions like hers and the 'dog-whistling' accusations around Trump.
