if this is a good argument then what does it say about gay marriages?
Do we not also allow people who have a genetic disorder and have an increased chance of passing along the disorder to have children? Do we not allow people with Tay-Sachs, or muscular dystrophy, or any other heritable disease to have children? We can't say we're protecting children from genetic disorders when in every other way we allow it to happen anyway. The only reason incest is illegal is the "ick" factor. Besides, they can just get an abortion...
Regarding polygamy, nowadays we appear to have serial polygamy, whereas we have multiple partners sequentially rather than all at once. Nevertheless, polygamy as we think of it still has no good counter-argument other than we think it's wrong. There is no argument one can make against these two scenarios that also wouldn't apply to gay marriage or any other form of legally allowed marriage.
