[1] Schlenker argues that the Stallion as sexual object occupies a position lower than the "cooler" in what he terms the Choice/Worth Hierarchy; as a sapient being who is required to sexually service mares, the Stallion is denied the choice of consent and identity, in the process becoming the passive victim of the mare's oppressive desire; whilst the cooler, as non-sapient, non-sentient entity, has no will and thus is not required to suppress its identity in order to feign consent under duress.

[5] Despite the references in Chapter 10, the study which identified Snugglepuff-Alondro syndrome as the cause of the Pony gender imbalance was severely flawed and utilised incorrect statistical methods. Current research indicates that the identified cause - the triploid foetus - was part of a longer process of “correction” to apparently non-viable foetuses that appears to repair missing or damaged genetic material through a process of transgenic cloning from the closest viable source, usually the mother. The effect is not environmental: ponies appear to express the same symptoms wherever and whenever they conceive. It is also indiscriminate and, once active, has a high probability of replacing the male sex chromosome with the female equivalent after apparently interpreting the male chromosome as damaged in some way. Why this would be so has yet to be determined.

The effect has been provisionally named Berry-Baltimare’s Post-meiotic Nucleic Restructural Transgenesis, based on studies by Professor Tinkling Berry and Doctor Buddy ‘Cuddles’ Baltimare of St Furrowfoal’s University Hospital.

[13] The idealised traits of each tribe were compared to the six Muses - not to be confused with the Muses of the ancient Roaman tradition - often associated with the Elements of Harmony, though they are not particularly closely related. The Muses, by tribe, are: Pegasus - Duty and Chivalry; Unicorn - Benevolence and Wisdom; Earth Pony - Diligence and Craft.

[15] A typical example is found in the PRINCESS2 project management methodology, which posits that the management of personality is at least as important as the management of ability in successful project completion, and proposes a number of solutions, including the "Winning Pit" team-building exercise, in which members of the group are pitted against one another in competitive sparring until one is left standing, after which she is ritually pelted with flour. What this has to do with personality management is never explained.

[21] Baltimare in particular is famous for its early history as an earth-pony city that was almost exclusively female for over a hundred years after its foundation. The city is most famous for the invention of the cooler, as well as the rather less popular "icepacker".

[26] See The Crown vs Sixrow, Olli, Herta, Elrose, Abee, Brier, Laycee and Golden Promise (1026) 9 PBD 177, where a herd was successfully prosecuted for bringing their eldest colt back as a stallion, "denying his choice" and "denying other mares his use".

[27] Best exemplified by the fictional account The Adventures of Hinnyburro Jennet, which documented the adventures of the titular character as she travelled from the fictional border town of Potters Mountain to Manehattan and back.

[29] Ignoring the obvious example, the aforementioned Greta Kinstrong has maintained a relationship with two of her colleagues (Professors Double Blind and Merry Cox-Apple) for nearly eleven years, though it was kept hidden for much of that time.

[30] The criticisms are too numerous to mention, except by reference to their particular focus. In Foalish Behaviour, and similar works, the complaint is that tactile behaviour encourages early sexuality in "innocent" foals that leads to a promiscuous and disease-ridden society, whilst in works such as Intimacy in Separation, the argument is that society lacks the ability to understand true intimacy because if a lack of "separateness" and intolerance of isolation.

[31] Most notable is the Duchy of Canterlot, which has been held by the male line of Blueblood for much of the Unification Period, following the transfer of the capital in 232CE
