Excuse me! Loads of Western European countries allow full incest (e.g. Belgium, France, Spain, etc.) so let's not pick on us Brits for allowing cousins to fuck.
I'm partially agreeing with you, but just because other countries say it's OK, it doesn't mean that we should.
Haven't looked at the data, but still, 15% risk is high. From a social a health care perspective, this is horrible for those children too.
On the other hand, you can have marriage without children and children without marriage.
Unless you start punishing them for having children, it's naive to ban marriage.
not making illegal and support from the national health service are vastly different things. 15% is a disastrous rate for public health.
But it's not a 15% risk. Unrelated couples have a 3% chance of having a child with a birth defect while cousins have a 5% chance of having a child with a birth defect.
Isn't the problem being that the probability increases with each subsequent generations? That's why having a child with a cousin should be discouraged, to prevent the accumulation of bad recessive genes.
If you have one person with recessive genes and one person with dominant genes, then the baby will have the dominant gene. So if the grandparents were cousins both with recessive genes it wouldn't matter, as far as I know.
The thing is, with subsequent incestual generations, the likelihood of the recessive gene manifesting increases a lot. So, the problem is not a single generation of incest, it's the normalisation of incest that might lead to multiple generations doing it.
Oh I see what you're saying. I did some reading earlier that said that in a lot of places 20% - 40% of all marriages are to first cousins.
Yeah, plenty of places where first cousin marriages are still not uncommon.
theres also dominant alleles that are the disease state, it also gets complicated when theres partial penetrance since its only half an half.
The stats I saw show a 2.55% risk across all UK births. So a bit under 3%.
US yanks in red states too.
"Brits are like US Southerners" is, arguably, a worse insult then calling them incestuous.
For who? The Brits or the southerners? Lol
Whichever has more teeth
It's a fun stereotype, but you may find this map interesting
https://en.wikipedia.org/wiki/Cousin_marriage_law_in_the_United_States
Fun fact: Most of the places it's legal in are blue. Alabama, Florida, North Carolina, and South Carolina are the only red states it's legal in, out of 17 total states. If we include states where it's conditionally legal (usually based on age/fertility) it's Utah out of 7 states.
It's more about immigrants
Define "full incest". Pretty sure siblings are not allowed
Pretty sure they are. Incestuous relationships between consenting adults (with the age varying by location) are permitted, including in the Netherlands, France, Slovenia, and Spain. Why not check before making such a statement?
Not only wrong, but also childish about it. First, this topic is about marriage. They are not taking about letting them be in a relationship, but marriage.
And marriage between siblings is not allowed in several countries you mentioned, which you would know if you checked instead of being "pretty sure".
Not go be a wrong ass somewhere else.
Oh do fuck off, there's a good chap.
