If we consider how more powerful are individual citizens in a direct democracy compared to a representative democracy, the indirect power (of nagging her male relatives and friends, to directly propose laws and vote on them) an average Swiss woman had before the 70s probably still exceeded the direct power (to vote for one of the few pre-approved people once in a few years) an average woman has in any other democracy today.
That is a really absurd statement. If you can't vote, you can also not run for public office. The way you enact change in a representative democracy is to organise, create a party and then get elected, or to join an existing party and rise in the ranks. Some parties in Germany have a 50:50 male / female leadership split. I personally know several women that were active at the local level and ran for public office. A female acquaintance of my parents was state education secretary in the 90s for a while. None of that was possible in Switzerland on the federal level before ~1970.
