Why do people hate gays?

I see where you're coming from + why you think it's one sided But in reality it's just you don't know what you're talking about at all (gender is a concept invented by society, sex is about the parts you have down there) + people get frustrated when they talk to others that didn't even bother to research the topic they're talking about, especially when it involves them + the discrimination they've faced (sex roles??!? literally not a thing like unless you're talking about how men physically penetrate women to produce a baby???)

Millions of years ago living creatures divided asexually. They then evolved to produce sexually as a way to produce more resilient offspring so that life as a whole could survive. The biological sexes are a way to share DNA information so that the species doesn’t die off. I don’t think nature cares what individual members of the species does as the only thing natural for nature is that the species survives and evolves. Gender roles are socially constructed roles, behaviors, activities, and attributes that a culture considers appropriated for men and women. There are advantages to being tied to gender roles, or the species would have abandoned them long ago. Even if homosexual men and women get married, they will create a new cultural norm and have their own defined roles.

Probably since genetics has made men physically stronger and woman needing to be at home and protected by the fact that they spend nine months with another human in their uterus. That's why I mentioned that gender roles are advantageous to the species.

I do agree that we are suited for certain roles as they are advantageous to the species. Looking at how chimpanzees and bonobos form their gender roles in a similar way supports this. However, you also need to take into account the setting in which we live. Take for example that humans as a species have spent the majority of their time on Earth as hunters and gatherers. They had a specific set of gender norms then. After adopting agriculture, we adopted a different set of gender norms. Now we have a setting with the internet, in which humans don't need to hunt, and their is no need for the gender roles of the hunter and gatherer era as they are obsolete to the setting in which we live. So to summarize: Genetics created certain gender roles advantages when we as a species were hunters and gatherers. That explains why most cultures have similar gender roles. The settings have changed, and new gender roles are created to navigate and adapt to those changes. Genetics and nature obviously play a role in how we as a culture define gender roles. But they are nonetheless defined by humans.
