I do think that kindergarten teachers being all women is a big problem. If I have a son someday, I would want him to have some good male teachers that he can look up to from a young age. I had one in 5th grade and it really helped me.
Actually, it's becoming a pretty big problem not just for kindergartens, but for K-12 teachers in general. K-12 is completely dominated by women, while colleges and universities are split between STEM (male professors) and liberal arts (female)
Do you have a source for the gender split among STEM and liberal arts professors?
If you're a man, and say that you want to teach kids "people" will suspect you of being a pedophile.
Yes, and not if you are a woman. Is this 'female privilege'?
No, but it's one of the obstacles to overcome if you want more male teachers.
