If Obrador wants to push it to the point of violence...so be it, all the while making it clear that that is his decision and one he will bear the consequence for. Then begin governing and ignore the guy unless he forments sedition and violence.
If they give into this guy, whatever vistage of a constitutional repubilc they have remaining, will be destroyed.
Fox already started down that road when he let himself be chased away from his podium for the state of the nation address (or whatever they call it). I got sick over that one.
