I think you are confusing cause with symptom.
Many times in the past it was more likely that the women were more conservative. It is generally turned now, but that is not a hard fast rule of history. In fact, women here are just as likely to be conserv as liberal. We are not monolithic.
Hey, I’m just looking at every religious group that didn’t admit women as clergy leaders and then did so that I know of. It’s not like you hear about any of that became more conservative after or even remained as orthodox as they were at the time. If women clergy leaders have nothing to do with it, shouldn’t there be some group out there that are really conservative/orthodox that has female clergy as leaders?

Back when I was an Episcopalian, I was a member of a parish that was the 'training parish' for the entire diocese. All newly ordained priests/esses served a term in our parish for OJT. So over a period of about 28 years I saw every single priest ordained in the Diocese of Atlanta.
ALL the women were liberal, and 99% of them went to seminary for one political reason or another - to prove a point, to support feminism, or because they were lesbians (that one at least got fired, but probably wouldn't get fired today). With one exception, they were unable to administer a parish or to make a 'command decision'. That one was still incredibly liberal though. She eventually left the parish she got and wound up running a homeless ministry on the south side.
