Watchtower uses the following twisted logic to equate receiving a blood transfusion, with feeding on blood:
Feeding is sometimes done by injecting nutrients intravenously.
Blood transfusions are carried out by injecting blood intravenously.
Therefore the intravenous injecting of blood can be equated with feeding intravenously.
Hence, true christians refuse blood transfusions in order to obey the biblical command to "abstain from blood".
Now notice how the same kind of twisted logic leads to the equating of an invasive examination by a gynecologist, with sexual intercourse:
Sexual intercourse is often done by inserting the penis into the vagina.
Certain invasive examinations by a gynecologist is done by inserting an instrument into the vagina.
Therefore such invasive gynecological examinations can be equated with sexual intercourse.
Hence, true christians refuse such gynecological examinations that are performed by someone to whom they're not married, in order to obey the biblical command to "abstain from fornication".
It's the same kind of twisted reasoning, isn't it?
Could this be a good illustration to help JWs wake up?
Maybe, without bringing up the blood issue, you can just use their own twisted logic to make the point that they should refuse invasive examinations by gynecologists. Then let the JW reason it out and explain to you why you can't equate such an examination with sex. Then once they've reasoned it out, use their own reasoned out explanation against them by applying it to show that injecting nutrients is similarly not equivalent to injecting transfused blood.
What's the difference between sex and the gyn exam? Purpose and intent. The purpose and intent for which the penis is inserted during sex, are completely different to the purpose and intent for which the instrument is inserted for the examination. The same applies to injecting food nutrients vs injecting a blood transfusion.
