Why were some greeks shocked by the lives of spartan women?

Some Spartan women were treated with some equality in contrast to the Greek world
 

Usually Greeks gave women no rights and did not let them own property or even choose their own husbands. This was the case in one of the city-states, Athens. Sparta, however, wanted warriors who could fight in case of an emergency or war, so they trained women just like men, both in a cruel way(they were taught to not cry or complain when they got severely hurt like a whip). However, because women had more rights, it shocked all other cities especially Athens. This is one of the main reasons why Sparta and Athens (the two Greek city-states) were considered as two very different cities. I hope this helped!!
