1. Your comparison to the gassing is absurd. Even in the ’40s anyone who supported gassing knew it was an extremist/murderous idea. No less than today. They knew, then, if they lost the war they’d be charged with war crimes.
The supporters of the status quo on women’s suffrage pre-1920 were a) in the majority until at least 1915 and b) did not consider their opposition to changing the law on suffrage as being extreme; indeed they considered the supporters of suffrage, who wanted to change the voting system to something never before done in history as being the extremist and c) even supporters of women’s suffrage (pre-1920) did not consider the opponents of the change as being extremists. They obviously disagreed with them but the opposition was seeking to maintain the status quo.
2. Let me assure you 100% b’emunah shelamo with complete and total honesty that I earnestly believe that women’s suffrage was a mistake to have been granted in 1920, that it has had many more negative than positive consequences as a result of it having been granted, that it would be beneficial to society to revoke it today and that if I today had to cast the deciding vote as to whether to continue or to discontinue it I would undoubtedly cast the deciding vote to revoke it.
As an aside and bonus, and this may be more difficult for you to accept but I also truly believe it, I would estimate that most Chareidi men agree with me and, if casting their vote behind a curtain (i.e. in private as voting traditionally is done) they’d vote to revoke it too. But I also think that most of them wouldn’t admit this in a survey.
