There isn't much about Fran Blanche on the farms. My initial impressions before knowing about the troonery.... The hair. It always looked unnatural, sickly, and thin. Not attractive looking at all. Most woman would know when to switch to a shorter age appropriate hair style when their body can't support healthy looking long hair.
The show and tell level presentation of the videos are bit shallow and lacking in depth. EEVblog and bigclive go deep to theory and schematics, but most look beyond this because this is a "woman" talking electronics and part of the novelty of the channel.
Then in some videos I noticed "she" was going into full blown pity solicitation mode from time to time. Some women do this, but almost all stinkditches do.
After knowing about the troonery, it all made sense. Goes to show that an actual woman having any intermediate or above knowledge in computers or electronics doesn't actually exist in nature. If you find one there is 95% chance "she" had dick and balls at one point.
