1-2% includes people who have extremely minor deviations from the norm and requires you to use the most strict biological definitions of 'male' or 'female' that we could possibly use. The vast majority of these 1-2% are still easily assigned a gender.
From your wikipedia article-
> If you ask experts at medical centers how often a child is born so noticeably atypical in terms of genitalia that a specialist in sex differentiation is called in, the number comes out to about 1 in 1500 to 1 in 2000 births [0.07–0.05%]. But a lot more people than that are born with subtler forms of sex anatomy variations, some of which won't show up until later in life.[132]
There are some percentage of people who aren't overwhelmingly male or female, and it's important to consider them with our speech, but I don't think 1-2% is a fair representation.
How courteous of you to assign gender definitions to people based on their chromosomes! Binary gender theory is the tail wagging the dog; it's backwards reasoning used to prop up outdated cultural beliefs.
Those people who need their chromosomes analyzed are part of the 0.07-0.05%, not the 1-2%
I imagine we would agree about the importance of respectful social interaction with those who don't fit within gender norms. I'm probably on your side here, but it's important to have these discussions using good facts.
