Why Can’t Two Gay Brothers Marry?

CharismaNews 23 October 2015  
One of the strongest arguments against consensual adult incest is that incestuous unions could result in children with genetic defects, but since that concern wouldn’t apply to same-sex couples, an Irish political leader has argued that gay cousins should be allowed to “marry.” And that only begs the next obvious question: Why not gay brothers or gay sisters?

As reported in The Irish Times, Independent Senator David Norris, himself gay, “has said that gay cousins should be allowed to marry each other following the same-sex marriage referendum.”

“It would not take a feather out of me if two cousins married each other,” Mr. Norris said. “What is the problem with that?”

So, no sooner does the Irish Legislature officially announce the legalizing of same-sex “marriage” than an Irish Senator calls for gay cousins to be allowed to marry.

Yes, “Mr. Norris said the regulations covering cousins marrying were introduced to protect the genetic pool, but that this would remain relatively untroubled by same-sex marriage.”

Then wouldn’t the same line of reasoning apply to gay brothers or sisters who wanted to “marry”?
