If the inability of gays to produce children is irrelevant to allowing them to marry, then the increased likelihood of difficulty producing children can't be used as an argument against sibling marrying either.
But siblings aren't the only ones with genetic difficulties with reproducing. I have a friend who married and had a child with cistic fibrosis. After the fact they found out that they had an increased chance of any further children they had also being born with that life shortening and debilitating condition. You might be shocked to learn they didn't immediately get a divorce.
Sibling marriage is more like an extreme sexual fetish, as others have already suggested. You don't really need to legislate against them because they have very little general appeal. In fact, making them more forbidden would likely have the opposite effect.
That doesn't mean every unusual sexual fetish should be tolerated. When there is a victim, as with children, prohibition is required. Sibling marriage can safely be ignored and tolerated. However we wish to legislate in relation to the marriage of people with genetic incompatibility such as my friends with the CF child should suffice for siblings who wish to marry. Inform or forbid.
I would lean toward more tolerance and not forbid it. No imminent stampede toward incest is likely to result from making it forbidden. And there will always be some drawn to it if we do forbid it who might not have been otherwise.
