Not all biological variation is classified as intersex.

You can change a lot of your 'secondary sex characteristics' intentionally. This is much easier than removing a limb, and even easier than adding a limb.

Okay, but other biological variation is clearly not relevant to the discussion.

No, I am specifically talking about biological variation in sex characteristics. This is common, and it's not surprising if someone is within the range of "the opposite sex" for one or several sex characteristics.

There are men under 5'4", women taller than 5'9", women with high testosterone, men with low testosterone, men with breast tissue, etc.
