If you're only looking at it from a medical perspective, you probably don't take abstinence seriously as a preventive measure. Therefore, it's doubtful that you're open to being educated on anything. Few MDs are. But we don't have a particularly high regard for "experts" around here. If you have an argument to make, please post statistics and sources. Because, "I'm a doctor" won't do.
-Abstinence is absolutely the best preventive measure, no argument there. However, many people will not consistently abstain. In this case, we're talking about a married couple where one partner is infected, and I do not believe all married couples in this situation are willing to permanently abstain.
-I expressed interest in learning more about the theology. If this conversation should be limited to those already conversant with the theology, I'll bow out - I didn't realize it was a closed conversation.
-At no point did I say "because I'm a doctor."
-You can see information from the CDC at this link, including: " Latex condoms, when used consistently and correctly, are highly effective in preventing the sexual transmission of HIV, the virus that causes AIDS." The page explains why it's hard to get exact statistics.
Because, "I'm a doctor" won't do.
I suggest you take a refresher course on what God teaches us about humility. You might consider foregoing your "preaching" as part of the course.
Your comments were pompous, arrogant and self-righteous. Shame on you!
