So exactly how is a Doctor providing treatment to a patient with STDs relevent to that? The Catholics are not saying that it is a sin to treat people who HAVE sinned. They don't place a confession booth at the door and require that everybody have a clean soul before they are allowed to enter.
Mrsltg is saying that there is no sin involved in giving them the drugs to treat STDs or in providing them with other medical care. It is not sinful to treat somebody because they are a homosexual either.
You are very much twisting her words.
The sin involved in the Morning After Pill is that it is possibly ending what they consider to be life, or preventing a life. Even though it is a choice of the patient to take the pill, providing them with the avenue to obtain the pill is a facilitator.
In their eyes it is like having somebody walk into your office, announce to you that they want to kill their spouse, and then requiring you to pull a handgun out of your closet and give it them.
