I'd argue the opposite, everyone does it to some degree or another on every topic. There is a near-infinite degree of nuance to any given topic. You can slide up and down the ladder of abstraction depending on your own understanding and your audience. Some people have the patience and curiosity to develop a more nuanced understanding of a topic and refuse to generalize in discussion, which has the effect of excluding those with a less nuanced understanding of the topic; others generalize faster, possibly for rhetorical purposes and to align with people lacking a more nuanced understanding of the topic. This leads to an amplification of the least nuanced position that the majority of people support. You see this effect in almost any community. To avoid this, you'd have to devise a way to exclude people who refuse to develop a more nuanced understanding of any given topic (i.e. lack curiosity).
