I feel like were straying back into "sex and gender are the same thing" territory which seems reductive to me.
Not sure why we would focus on algae when we're clearly only talking about humans.
I get that intersex/other genetic disorders exist. But I still don't get how that breaks the rule instead of proving it. The rule is that humans have two arms and two legs. Just because there's one armed people doesn't mean that rule is broken. It means they're an exception to that rule.
Why is readarr broken?
