The political Right was more dangerous than the radical Left because not only was the Right equally as extreme, but they were entrenched in power. The Weimar government and constitution allowed the civic service and the judicial system to remain untouched for the most part, keeping those previous in government with power. Most of these people were elites of the political Right from the prewar society who wanted to maintain their position in the social hierarchy. In addition, because the entire government was new, unsettled, and shaky, the deep political knowledge base of the previous government allowed these entrenched political elites to exercise powers as they saw fit based on their previous experiences. Their political experiences, familiarity with the system, and cooperation created a group of elites that already knew each other, wanted to maintain the status quo, and kept as much power as possible in the unstable establishment of the Weimar Republic.
The military elites were enabled to commit violent acts against the left by the court system that was predisposed to their views. They faced little resistance from the judicial system, who supported their actions against dissenters and political opponents. Gumbel chalks their murderous actions up to “the psychological brutalization of the war, in which the life of the individual was no longer allowed to count.” Although I think war experiences and skills did contribute to the actual actions of murdering political opponents, it does not account for their motives. In most societies, murder is an unacceptable action that is punishable by law, as it was in Weimar Germany. However, in the event of conflict, in an average community, murder is not the first path of action generally taken. Though their effective techniques and mass executions were influenced by military tactics and skills, the premeditation and implementation of killing in society showed just how comfortable military elites were in their entrenched positions of power.
In addition, the Right was a different kind of radical. Instead of being loud and up-front about their demands, they subtly found ways to maintain power and attack the republic at any opportunity. Whether it was abusing their relationships and connections in the court system to get away with murder, or blaming the Left for their horrible, socialist ideas, the Right managed to keep the attention of the public focused on the radical Left. The Russian Revolution also helped keep the Right out of the spotlight, making the public fear a communist revolt much more so than the prewar status quo. I think that their position too was automatically more favorable because humans generally dislike change. Maintaining the status quo versus introducing a completely new society that is the extreme opposite to what is familiar would make people nervous. Even if they supported the new system, new, unfamiliar ideas are scary simply because they are new, let alone if these ideas had just violently taken over a nearby nation. The fact that at least on the surface the Right advocated for a familiar, if unsuccessful, system automatically made them less threatening to the public than the radical, communist Left.
