The sign doesn't mention any gender or political identity. You're going off on an irrelevant tangent.

But I'm happy to talk about what you want to talk about since it seems to really upset you. First, I think it's important to make a distinction between sex and gender. There really only is 3 sexes. Male, female, and intersex (hermaphrodite) which is very rare. Gender is not the same as sex. It's more of an identity or personality. There are more masculine females and feminine males. Some people are asexual and androgynous. As far as I'm concerned saying there's 2 or 3 genders is fine with me. Male, female, and androgynous/asexual/intersex.

I don't believe there are a bunch of genders and find the idea silly. But you're using a common partisan smear tactic of taking a fringe person or position and trying to smear 82 million people as having those beliefs. I don't think most people think about or care about gender. Personally, I don't care. If I come across a goofball in real life that believes in 70 genders, which I never have, I'd just roll my eyes and keep it moving. These are not big problems to me. I care about ensuring people with illnesses have access to medical care at a reasonable cost. Transgender people are a fraction of a percent of the population. I want them to live free of discrimination but apart from that I don't think about them.
