Not OP; but I would define it as a cluster of specific and strongly held opinions on several topics, such as race/ethnicity, sex, migration, climate change. These opinions cluster together, and produce certain recognizable behaviors including speech patterns, speech taboos, and aggressiveness towards people who do not share these opinions.
