And yet Democratics encouraged and even participated in blocking the Supreme Court confirmation vote using... a march to the capital and overrunning capital security forces and successfuy occupying every space they attempted to reach.

Why shouldn't any of them been shot?

Both were confirmations to the highest level of office in their respective branch of government and both were staged by political opponents protesting and admittedly attempting to block an "unjust" transfer of power.

If "peaceful protest" vs "riotous coup" can hinge on the fact that your ideological allies could only have been there to "righteously have their voices heard" but ideological opponents must be there as "murderous usurpers", then your sympathetic reasoning might be better described as paranoid delusional projections.

Let's remember that it was Eric Holder and Bill Clinton who pardoned a woman who literally bombed the capital building.
