The thing about inbreeding is that it isn’t an instantly bad problem. The Habsburg dynasty was all about doing the nasty with cousins for a number of generations. It took a few rounds before the Habsburg Chin developed. Records also indicate that sister marriage was a common royal practice in pharonic Egypt.
It’s all a matter of probabilities and compounding problems. The first generation of inbred kids will probably turn out ok. With the second generation things can start getting sketchy. The more generations you go, the more likely you are to get Crimson Tide fans.
This is also why populations under a certain size can be problematic. When the family trees of a population start looking like brambles, problems start sticking out like thorns.
Oh they down bad.

what type of nose is that?
The result of inbreeding
The obvious workaround is fuck’em outdoors!
That’s a member of the Habsburg family. Known for generations of inbreeding.
There’s also the blue Fugates of Kentucky if you want another example of why limiting your gene pool is bad.
Wait a minute. I was just trying to choose whether to have chocolate or vanilla pudding while casually checking Lemmy. How did I go from almost choosing chocolate to finding out that there are people openly chitchatting about impregnating their daughter with the same tone as if they were talking about what they had for breakfast?
Genetically, as someone else pointed out, it’s not a huge problem as an occasional thing. Ethically? It gets dicey.
Also I suspect that most of the posts on r/inbreeding are fictional. The “niece” and “uncle” have identical writing styles, for one.
