Just think about it

honey, women can be in the army as well.

It wasn't nearly as common 100 years ago though.

Not really back then. In world war 1 era stuff womens role in the military was pretty much only as nurses.

you're totally right, but it isn't fair to conclude that we wouldn't be fighting. I mean, I'd rather not fight, but maybe, 100 years ago, I would've fought.

But you wouldn't be fighting because women and men were SEPARATED. You wouldn't see any real fighting. You would see men come BACK from fighting, but that's it. There was almost no way you would end up in the front lines.

Women weren't allowed to fight back then

"almost no way" means that there's still a possibility

read some books people, Milunka Savić- the true Mulan. Maria Boczkariowa- very important in russian army then. Flora Sandes- the only british woman who was fighting. Ecaterina Teodoroiu- also very brave. Aleksandra Kudaszowa- she was always in the first row at a battle. And finally Maria Błaszczyk- she was 17 when she joined the army and was killed by russians. So even if they weren't allowed, they did fight.

I don't think anyone is saying it didn't happen at all, it just didn't happen with as much frequency as now. Women have been pretending to be men so they could go to war for a while.
