The rection to lots of the gender issues in France has been interesting. My partner's family moved to France (not Paris, though) 20 or so years ago, and all of their friends were deeply interested in the coverageof the Cass report, horrified that the UK had fallen so far, and couldn't understand that there would be hospital units dedicated to this, even (especially?) from a family with an adult gay son.
There does seem to be a more materialist rational streak in the French national psyche, and it is encouraging that there has been such a grass-roots response to the banning of this book advert.
