I am confused. I thought the thread was about gender, and the reference to “social bullshit” and the statement “that outliers exist, doesnt mean anything” were statements in support of excluding transgender people from society. The 0.018% stat (rate of intersex if defined narrowly) is clearly a reference to sex, not gender. So now I am just lost.

I think things get taken too far in some contexts, but the underlying sensitivity is when you are talking to a person who considers themselves an outlier. Like telling someone with no legs that they don’t meet the definition of human and ADA is an abomination that should be repealed. Or telling someone diagnosed with conversion disorder that they can’t receive any physical accommodations, and can’t have any medical consults to check if their symptoms might have a different cause. I hope we can agree those would be insensitive positions to take.

I think they were trying to demonstrate the second type of dot should be increments of 10 - the missed step in the original answer - and both messed it up (started with an increment of 20 as you pointed out) and extended it way beyond what was required for the problem at hand.
