I'm getting dizzy from this merry-go-round.
I think Dan pulls apart Catholic Scientist's argumentation neatly with this little gem:
Right now? 100% of the people can enter fake marriages, but only 90% can enter real ones.
With gay marriage? 100% of the people can still enter fake marriages, but 100% can also enter real ones.
A lot of time on the potential for fake marriages, but not much spent on the difference in "real" marriages that will result from allowing gay marriage.
But, then, maybe this is all just an example of the no-true-marriage fallacy.
