Feminism is a tool of the ruling class, like racism. A way to turn the working class against each other instead of the ruling class, the owners. That’s why they give feminism so much space in the media and in universities, because it doesn’t really touch the real issues of the world, the billionaires and millionaires exploiting everyone and everything. It doesn’t threaten their rule over the world, by design.
My sex wasn’t allowed to vote in my country 120 years ago either - because only the nobles, the landowners, the priests and the bourgeois were allowed to. Most of the people, regardless of sex, were not allowed to vote.
It was also about slavery, at least partially. Abolitionism in the Empire was on the rise, and the colonies were afraid that the crown would abolish it empire-wide. Back in england they had ruled in 1772 that English law did not recognize slavery, so the threat to the american slave owners was very real. The so-called representative government they created was made to continue slavery and oppose abolitionism.
