Yeah none of those things are "normal". As I said, people are usually normal in some ways and unique in others. So someone being redheaded, the being redheaded is not normal, but in many other ways they may very well be normal.

Normality is overrated. We all have things that are not normal about us, and that's what makes us interesting.

What I don't like about the claim "being transgender is not an exception to the rule" (not the same as claiming trans PEOPLE are normal people, most trans people ARE "normal people" in that they have the same degree of unique/abnormal quirks as other people, even if their particular uniqueness is not shared by most), is that it's usually used as a push to redefine or abolish categories like "biological sex", because if "being transgender is not an exception" then that means that the categories of biological sex and gender that 99% of people fall into, have no meaning. And these categories are important medically and scientifically in many contexts. And while I do not suggest that trans people don't belong in feminism, they absolutely do, at the same time biological sex is an important aspect of feminism and women's oppression across history. The fact that some cis women are infertile, doesn't negate the fact that control of female reproduction has historically been a major aspect of sexism. That doesn't mean infertile cis women don't belong, neither does it mean that trans women don't belong (or for that matter trans men who want to be involved) or intersex people who were assigned female at birth don't belong, but there is a space for both gender identity AND biological sex in discussions of feminism, as it's like a Venn diagram, most women experience both, some experience only one. It's a form of intersectionality.
