Final answer:
A dominant ideology can lead to the suppression of contrasting ideas, as alternative viewpoints are silenced, marginalized, or discredited to maintain the status quo.
Step-by-step explanation:
When a dominant ideology exists, contrasting ideas are suppressed. A dominant ideology represents the predominant ideas, values, and beliefs in a society which often expresses and preserves the interests of the ruling class or group. In many cases, these ideologies become part of a hegemonic culture where alternative viewpoints tend to be silenced, marginalized, or discredited. This suppression can occur through various means such as law, custom, and exertion of political power. Examples of this phenomenon can be observed historically and in contemporary societies where laws have been used to reinforce the dominance of certain ideologies and suppress opposing thoughts, such as the restricting of political dissent in certain countries or the suppression of alternative scientific theories by the scientific establishment.
