Seriously, why jeopardize health of an innocent child? my parents weren't diabetic per se, and nobody had T1 diabetes in our family, but still I got diabetes at age of 16. I enjoyed chocolates, ice creams and cotton candies as a child, but I pity those who were exposed as a child, specially by maternal or paternal straight faulty genes, and I think that diabetics shouldn't be allowed to get married because of this.
