The feminist movement as a whole is very much against gendered norms about who should and shouldn't be a kindergarten teacher. Which feminist movements did you see fanning these particular flames?
This happened in Sweden, and in one article I recall reading the comment that "there is no need for male kindergarten teachers" from local politician from the left block which identify as feminist (current left block call themselves as a feminist government). The left block was also in power during that time which created those restriction for male teachers. One argument used to defend those restriction was that science showed that most criminals of this kind is male, and thus argued that male employees were higher risk.
It would be hard to say anything about "The feminist movement as a whole". At the time, no movement was stepping up in support of the male kindergarten teachers.
Your attack on whether his comment is 'thoughtful' or not is weak.
