I would add Dogma remains our greatest enemy, it can be argued that dogma is a product of ignorance.
Dogma itself isn't a problem. For example, the belief that the Constitution and the values it represents are the cornerstone of American society is a type of dogmatic belief. Dogma itself doesn't pose a problem unless dogma intertwines with fundamentalism, where the violation of dogmatic beliefs calls for unduly harsh punishment.
Dogma by definition is the acceptance of principles laid down by an authority as incontrovertibly true. This is a problem, you should only accept anything that you yourself have verified.
Dictionary.com lists four definitions:
1. an official system of principles or tenets concerning faith, morals, behavior, etc., as of a church.
2. a specific tenet or doctrine authoritatively laid down, as by a church
3. prescribed doctrine proclaimed as unquestionably true by a particular group
4. a settled or established opinion, belief, or principle: the classic dogma of objectivity in scientific observation.
Especially as in the case of the fourth definition, not every definition of dogma requires the negative aspects as you have presented them. The American belief in constitutional democracy and republicanism are both dogmatic, as is the notion of objectivity in scientific observation, as the definition points out. These are things society overwhelming accepts as good things, so the problem is not with dogma, it's fundamentalism. A global dogmatic belief that it is wrong to harm other individuals would be immensely beneficial to humanity, but there are religious fundamentalists to who believe harming others is justified by their religious dogmatic beliefs. The problem there isn't dogma, it's fundamentalism.
