One begins by considering this vital paragraph from the article one is criticising:
"This radical momentum came to a halt with Joseph Stalin’s rule in the 1930s. Abortion was made illegal. Capitalist programmes were vigorously recreated. The likes of Krupskaya and Kollontai, who had led the charge for radical institutional approaches to sexual and gender liberation, continued to criticise the various ways in which Stalin’s rule was destroying not only the gains they had won for women, but the socialist policies and practices developed since the revolutionary period. They were politically silenced and sidelined."

It seems to be a trend, as in the Weimar Republic that predated Hitler Germany, that progressive values are often overturned by a following authoritarian regime that then goes on to slaughter innocent people.
Could history repeat itself?
