......no....scientists have proven that with first cousins there is always a risk of abnormalities/brain damage and/or mental illness when inbreeding and having a child..the only thing scientists have said is that its less of a risk than brother and sister. Statistically it has even been shown that those who end up having normal children can even put grand children at risk of retardation or birth defects... but..its only continued because of the cultural background. Other than that it is considered taboo in most other countries due to the risks.

i dont mean to be rude in any way, i just wanted to imput as i live in south africa and my brother is a doctor here. it happens often that people have children by first cousin and even rape cases where their brothers and fathers give them children. in the cases of first cousin there are many many problems with the children. Of course not all of them but more than you would think.

Actually in my country or religion, you can marry your cousin who are NOT your first cousins. You can marry your second cousins or more distant ones. But you can't marry any cousin from your mother's side. So when people say, cousins who are married, they are actually very distant relatives so it doesn't even matter.
Why are people here so against a relationship between cousins?
Dude, i dont know if it's only here or not, but in my country you can marry even if you are cousins. Actually, i had a friend in middle school whose parents were cousins, lol
