That article is hardly conclusive. It states the biggest reason for the unpopular response was a belief that the incidence of traffic accidents involving young children walking to school increased. It also states that wasn’t factually supported.

It also cites one opinion poll. And we have to keep in mind this happened FIFTY years ago.

I’m not even a permanent DST advocate. It’s just weird to me the link you shared does nothing to substantiate your position.

Update: my suspicions were correct — there was a public panic caused by parents groups that had no basis in fact:

> Considerable opposition to observing DST during the winter had come from school groups, such as the National School Boards Association, which expressed concern over darkness during the morning school commute.[47][48]

> When members of Congress introduced legislation to repeal the practice, they stated it jeopardized children's safety, citing the deaths of eight schoolchildren in Florida since DST had been enacted a few weeks prior

Ironically:

> A meta-analysis by Rutgers researchers found that permanent DST would eliminate 171 pedestrian fatalities (a 13% reduction) per year
