In the history of the United States of America, there's a strange ban on women

The United States, which has always lived in democracy, freedom and equality, has not been as enlightened in its history as it is today.

No overly exposed swimsuits.

In the 1920s, women travelling to the beach were required to observe strict rules, and the bare area of their skin could not exceed a certain value.

In practice, some law enforcement officials have only been accused of measuring women ' s swimsuits with rollers, and offenders may be arrested.

Women were banned from Boston marathon until 1972.

In 1966, Roberta Gibb insisted on taking part in a long run without an invitation and without registration.

The following year, a woman named Katherine Switzer was registered under the name “K.V.

Switzer” and obtained a number.

A lot of men have expressed their anger at her, including the official Jack Semple-- He cursed her, tried to rip her number off, tried to scare her off the runway.

It was not until the adoption of the Equal Credit Opportunity Act in 1974 that women were allowed to obtain credit cards without a male guardian.

Previously, single women were (lawfully) denied credit cards, and only married women could have a credit card if their husband was a banker.

It has been illegal to employ pregnant women to work during pregnancy.

The pregnancy discrimination act was not terminated until 1978.

Previously, it had been normal for enterprises to dismiss pregnant workers.

It is estimated that approximately 40 per cent of employers would have insisted previously.

It was not until 1979 that NASA began training female astronauts.

In 1983, Sally Ride became the first female astronaut to enter space.

We're not allowed to sit on the jury.

In 1975, the United States Supreme Court ruled that women could be members of a jury.

Until then, it was considered that women could not bear the details of certain criminal acts and would be too emotional to make rational judgements.

I'm sorry
