This conservative libertarian does not support the juvenile Libertarian Party platform. I agree with your objections to the clause you quoted.
But the I question I raised in post #5 is something the juveniles should understand.
Post five ignored the thread topic, states already ahve gay marriage, and the federal government is recognizing those state marriages for federal employees and foreign gay marriages in immigration.
The question is how we outlaw gay marriage again, and keep polygamy from becoming legal.
Libertarian and liberal politics has already given us gay marriage with polygamy soon to follow, we want to end it and preserve normal marriage.
