Methinks thou doth protest too much...
I beg to differ. The positive or negative sign refers to the V/I (Volts divided by Amps) curve, which of an ordinary, normal, and rather boring resistor is positive. However, various components and circuits will produce a negative slope, and therefore a negative resistance, usually over a small range of voltages and currents. Putting two resistors in parallel produces a different V/I slope value, but does not magically change the sign of the slope from positive to negative.
There are few ladies and no children that read this newsgroup. I think it's safe to say that none of the active participants could be considered gentlemen by any standard. Perhaps you could do better if you address the audience of engineers, who might find it rather disagreeable to be conglomerated with the ladies, children, and gentlemen of leisure.
