No one should have answered the coward that started this thread. There is no reason to post something like this as an αnσnymσus. Besides, these αnσnymσus threads can easily be used extended forever by one person posting strawmen to make himself look good.
You make a good point. In αnσnymσus, it's very easy for someone to introduce and mobilize a number of sock puppets. It's a favorite tactic of governments to demonize the opposition toe planting people in the opposition to make them look bad. I'll refrain from further comment on this thread.
There's no proof that St. Emerentiana wasn't already baptized with water. During times of persecution, the Church commanded that catechumens all be baptized even though they would continue on in the status of catechumen to receive further instruction. They continued to be called catechumens even though they were Baptized because their formation wasn't complete yet. There's direct proof of this. There are numerous references to known baptized Catholics (including the case of a priest) who were spoken of by the Fathers as having been baptized in their own blood as a second Baptism that washed them of actual sin so they would directly enter Heaven without any Purgatory. So this is not conclusive proof of anything. Baptism of Blood, furthermore, is a completely distinct notion to the Fathers, with many of them believing in BoB but rejecting BoD. And they believed in BoB because they believed that it was the actual Sacrament, with all the "sacred elements", with blood supplying for water and the angels pronouncing the form of Baptism.
These types of quotes have been dealt with at least a hundred times already, but people keep slapping the same things out there as if they were new and provide a sudden smoking-gun proof of the position.
