I have no idea what you're even talking about in terms of gender ideology. Gender roles has always been a thing.
Middle Ages:
>first of all that spans like 1000 years and covers an entire continent. So we'll be talking in very broad strokes.
>The Catholic Church probably has some canon law in the issue.
>they didn't appreciate other religions/denominations which is why we had wars of religion in the early modern era. The only valid priests would be those who fulfill certain prerequisites.
>who is killing female animals to prove that sex can change? Where did you get that idea?
20th century
>first of all, skipping 400 years of societal change is not a good look.
>again, broad strokes as we are talking about millions of people spread worldwide.
>yes, there would've been enough men as trans men are a small minority even today.
>why would future generations blame technology, social media and weak minds of politicians? We don't even do this for devastating events like the American Civil War or either of the world wars.
You're not trying to figure out how it would've featured in the past. If you did, you would actually research the era.
