It's unclear if Captain Wentworth honestly thinks women require more care and better accommodations or whether he is avoiding women in general because of Anne. This line of Mrs Croft's is beautiful. There is a modern web series adaptation called Rational Creatures. I think this is an echo of Mary Wollstonecraft, Austen uses the term again when Elizabeth Bennet is rejecting Mr Collins proposal (P&P chapter 19)

The famous opening of Northanger Abbey describes Catherine Morland “as plain as any.” Yet from the list of qualities and habits that set her against narrative expectations—the Gothic and the sentimental—and social expectations—femininity and propriety—Catherine’s character ultimately emerges as unconventional, too. In seemingly trivial and funny details, such as her preference for cricket over “feeding a canary-bird,” the narrator intimates her inconformity with dominant beliefs about the nature of women. The canary alludes to existing associations between birds and women that underscored women’s lack of rationality and their supposed vulnerability.

In many portraits of the period, young girls were eroticized through their connection to birds, particularly when portrayed weeping for a dead pet bird, a sign of their loss of sexual innocence. Canaries, a favorite songbird in the late eighteenth-century household, were associated with young girls through their delicate size, beautiful and soft feathers, and prized songs [1]. At the same time, women’s musical abilities, as exemplified in Pride and Prejudice (1813) and Emma (1815), were a sure-fire sign of their marriageability: good singers made good wives [2]. Maturity didn’t save women from disparaging associations with birds. Spinsters were oftentimes portrayed surrounded by parrots and bird cages, the equivalent of crazy cat ladies [3]. By creating a heroine who is more likely to be found outdoors exercising than feeding a small, delicate bird, Austen disassociates Catherine from these sexist beliefs. Not all associations to birds were troubling, though. Songbirds figured in stories for young children to instill kindness toward other animals, as in Sarah Trimmer’s Fabulous Histories (1786). Austen’s contemporaries shared a strong belief that educating children to treat animals with kindness was the foundation for instilling sympathy toward other humans [4]. Yet, as Mary Wollstonecraft argued in A Vindication of the Rights of Woman (1792), a rational woman knew that compassion “for the bird starved in a snare” came second (or third) to compassion for her fellow humans.

Women were not allowed to address the court or testify in criminal cases unless there were special circumstances, including in the United States. The legal silencing of women in law courts was discussed in Mary Wollstonecraft's The Wrongs of Woman (published posthumously by William Godwin in 1798).
