Almost all Americans want to be democratic, but many Americans are confused about what, exactly, democracy means. How do you know when someone is acting in a democratic or an undemocratic way? Recently several groups have spoken out with particular bitterness against the kind of democracy that means equal opportunity for all, regardless of race or national origin. They act as if all human beings did not belong to one species, as if some races of mankind were inferior to others in their capacity to learn what members of other races know and have invented. Other extremists attack religious groups—Jews or Catholics--or deny the right of an individual to be an agnostic. One reason that these extremists, who explicitly do not want to be democratic, can get a hearing even though their views run counter to the Constitution and our traditional values is that people who do want to be democratic are frequently muddled.

[问答题]背景 某施工单位承建了天津市某医院门诊楼工程。地下2层、地上16层，钢筋混凝土筏板基础，地上结构为钢筋混凝土框架结构，墙充填为普通混凝土小型空心砌块。施工过程中发生如下事件： 事件一：本工程基坑深8.5m，北侧紧邻某住宅楼。经专家论证后的方案采用围护桩墙+预应力锚杆支护体系。整个施工过程对围护体系实施连续变形监控，对于围护桩墙顶位移监控值，施工单位与监理发生分歧，施工单位认为按二级基坑监控，监理坚持按一级基坑进行监控。 事件二：基础工程施工完成后，在施工单位自检合格、总监理工程师签署“质量控制资料符合要求”审查意见的基础上，施工单位项目经理组织项目技术、质量负责人、总监理工程师进行了地基与基础分部工程的验收。 事件三：普通混凝土小型空心砌块墙体施工时，施工人员先将小砌块充分浇水湿润，再将砌块底面朝上反砌于墙上；外墙转角处的临时间断处留直槎，并砌成阴阳槎，并设拉结筋。监理工程师认为施工方法错误，立即下发了整改通知。 事件四：地上框架结构存在主次梁，在主次梁交汇处，关于钢筋摆放上下顺序监理与施工技术员在理解上发生分歧，随后上报总监理工程师处理。 指出事件三中的不妥之处，并给出正确做法。
