You can condemn it, be fearful of it, and be specific with regards to the threat it presents. It presents threats. I assume the specific threat the poster was refuting (which I won’t throw my 2c on here) is that it posed a threat to materializing a new government in the United States, which is typically the top of mind threat when talking about coups. So citing the number of deaths is neither here nor there in assessing the validity that it was a legitimate threat to creating a new government and ending the previous one.
