"Always been here" and the left handedness trope seem to be at odds with one another too. No need to excuse a sudden spike if you have always been here.
It's actually more ironic because if you ignore the left-handedness graph they always post and post the one with the entire dataset their usage of the graph is destroyed because it shows left-handedness is a natural deviation that exists at some roughly general rate. The "spike" comes after a short-term suppression in the rate.
The one they always post:
The graph from the cited source:
And since
the Substack I grabbed these images from since they had the second graph helpfully did when you adjust it into the rate of change, the temporary situation is more obvious:
They make this error because they think there was centuries of left-handed suppression when it was actually just a couple decades affecting really only one generation.
Tony and all the others who use this argument SHOULD be showing a natural rate of trans existence that was
higher than now then suppressed at some point in the past and is
now returning towards normal. They can't because it's impossible. Nobody recorded data on something that wasn't conceived until the 1990's.
The left-handed reality is really what should frighten them, that the trans spike
will look like left-handedness. When it returns back towards zero after the fad is over rather than establishing a new normal (that's also the historic past) of 20% of the population being trans.
