近几年各地频现聚众淫乱行为,从而引发了学者们对聚众淫乱罪的存废之争。废除该罪者多认为聚众性行为是一种自由权利,该行为应该由道德进行规制而不应由法律进行调整。本文通过从法理学的角度分析道德与法律的关系,论证了目前我国刑法中的聚众淫乱罪保留的必要性。 In recent years, frequent occurrences of promiscuous promiscuity all over the world have triggered the scholars’ dispute over the crime of collecting and prompting sexual promises. The abolition of the sinner believed that polygamy was a free right and should be governed by morality and should not be adjusted by law. By analyzing the relationship between morality and law from the perspective of jurisprudence, this paper demonstrates the necessity of retaining the crime of gathering unwanted promiscuity in our country’s criminal law.
