wow look here's another wikipedia article about "phobia"

https://en.wikipedia.org/wiki/List_of_phobias

The English suffixes -phobia, -phobic, -phobe (from Greek φόβος phobos, "fear") occur in technical usage in psychiatry to construct words that describe irrational, abnormal, unwarranted, persistent, or disabling fear as a mental disorder (e.g. agoraphobia), in chemistry to describe chemical aversions (e.g. hydrophobic), in biology to describe organisms that dislike certain conditions (e.g. acidophobia), and in medicine to describe hypersensitivity to a stimulus, usually sensory (e.g. photophobia). In common usage, they also form words that describe dislike or hatred of a particular thing or subject (e.g. homophobia). The suffix is antonymic to -phil-.

huh, that makes a lot of sense to me. More sense than whatever you're implying about the interactions between e.g. oil and water having something to do with the left and mental issues.
