Bigots against consanguinamory frequently bring up rare examples of individuals or an isolated family in which there has apparently been many generations of close inbreeding, and the problems these individuals or families have. This is supposed to be justification for discriminating against the consanguinamorous.
This is as ridiculous as saying something like, "Look up
Scott Peterson" as to why non-consanguinamorous relationships are bad.
Most consanguinamorous relationships are between people like your neighbors, co-workers, classmates, and "ordinary" people you know. You know healthy, bright, attractive, friendly people whose parents are close genetic relatives, whether you know their true genetic parentage or not. They might not even know. Meanwhile, there are people who have inherited serious genetic diseases and their parents were not close genetic relatives.
It is also important to remember that "birth defects" can be caused by many things, including environment, abuse, substances ingested by parents, and other factors.
Two or more closely related individuals wanting to share sex, romance, a residence, or marriage is not the same thing as many generations of isolated inbreeding.
We have examples. For example, we can compare births in US states that have no criminal laws against consanguinamory to states with strict laws against consanguinamory. Spoiler: states that do not criminalize consanguinamory do not have a higher genetic disease rate than states that criminalize first cousins for having sex.
Instead of continuing the discriminate against lovers, we should be encouraging the use of modern science and technology to prevent, mitigate, and treat what is of concern.
It is also important to reject ableist bigotry that dehumanizes people with certain genetic conditions.
This blog does not encourage anyone to literally or figuratively isolate themselves from the rest of society and inbreed in perpetuity for generation after generation, so citing examples of that misses the point.
There simply is
no good reason to deny
