On today’s episode of people who should know better, a 21-year-old woman discovers her grandparents were related and decides her cousin blames disability on family incest from generations past. What started as innocent wedding planning turned into a family meltdown that left everyone speechless.

When Family History Gets Uncomfortable: The Backstory

Our main character is a 21-year-old woman attending a family lunch with her parents and cousins. They were innocently adding wedding dates to their calendars when the conversation took a sharp left turn. Her grandmother started explaining family relationships in their native language.

Meanwhile, the young woman was feeling chatty after a good meal. However, her loose tongue was about to get her into serious trouble. Her cousin with intellectual disabilities was also present at this gathering.

The Moment Everything Went Wrong

Initially, the conversation seemed harmless enough. The woman asked her dad how they were related to people on the wedding invites. Then her father dropped a bombshell about their family tree.

As it turns out, her grandfather was actually her grandmother’s uncle. Furthermore, this meant her grandmother’s mother and grandfather were half-siblings. The family had a history of incest that nobody talked about.

Consequently, both she and her cousins started making disgusted faces and gagging sounds. The parents tried defending the past generations’ choices. However, this only made things worse for everyone involved.

Eventually, the conversation reached its breaking point. The woman blurted out facts about incest causing intellectual disabilities. Her cousin then said this explained his brother’s condition, and she immediately agreed.

What Reddit Said

Most people said she was absolutely the asshole for connecting ancient family history to her cousin’s disability. However, they acknowledged that discovering incest in your family tree would be shocking and uncomfortable.

Some pointed out that intellectual disabilities from incest three generations back are essentially impossible. In addition, many commenters noted she was making fun of someone who already faces daily challenges.

A few suggested she desperately needed to grow up and learn when to keep her mouth shut. Nevertheless, some understood the initial shock of learning uncomfortable family history.

The Verdict

Overall verdict: OP is definitely the asshole for suggesting her cousin blames disability on family incest. Therefore, the lesson here is simple: never connect someone’s disability to family genetics unless you’re their doctor.
