Very very very silly and ill considered of me to get involved at this point, but I'll give it a brief go by stating what I see to be the two major positions on this thread along with an idea on what they're not connecting:
CFLarsen:
1. al Timimi did not commit treason
2. Coulter did not commit treason
3. Coulter made remarks analogous to remarks made by al Timimi
4. To be consistent, the US legal system should be brought to bear against Coulter in the same manner it was brought to bear against al Timimi
Most everybody else:
1. al Timimi may or may not have committed treason but seems to have been convicted of it. Barring evidence to the contrary, we'll accept that.
2. Coulter did not commit treason, hasn't been charged with it, and hasn't been convicted of it
3. Coulter's remarks are not analogous to the remarks of al Timimi
The breakdown is in the analogy between the remarks. If analogous, CFLarsen's question has merit. If not, it doesn't.
Personally, I agree with most everybody else. Coulter's remarks are reprehensible, disgusting, bigoted, idiotic, irresponsible, and worthy of all the scorn we can heap upon them, but they do not constitute treason in that, in context, they do not advocate harm against the US. This will be the sticking point with CFL who thinks otherwise.
