An
adage used as a psychological tool to expose bias.
The key portion is the last word, which used in this context can be interpreted either as a statement of truth (i.e. oranges are orange) or as a pejorative insult (Those shoes are gay). Essentially it will trigger people who are easily triggered. The point of doing this is to show that an inherently
unbiased statement is interpreted by the individual to follow their own rationale, often time exposing their bias towards negative interpretation.
