Hi

* Astrophage is more like a virus that either alters people, causing them to commit crimes or violent acts, or a power that supervillains are starting to use.

* Grace is still a middle school teacher who got bitten by the spider, obviously.

* Adrian is the one who stitched up the suit (the Aunt May of this universe).

* He has all the perks of a normal Spider-Man, but he's still Grace, so he's incredibly clumsy. He does have a super-strong spider sense, and that's what saves him 100% of the time, but he absolutely does not have the agility. When adrenaline kicks in, he can do anything, but otherwise he'll trip over the most ridiculous things.

* He was wearing his yellow raincoat the first time he saved someone, so now he wears it over his suit (along with his white Converse).

* The spider was discovered by SHIELD (which is undercover as a scientific research facility that Grace works for part-time). After the original test subjects (who were only able to survive the spider mutations if they possessed a specific gene) were killed in an attack, Eva delivered the spider to Grace so he could be bitten before other villains got their hands on that power. (My boy gets unwillingly turned into a savior in every universe.)

* Simon is still an ex-convict who, in exchange for his freedom, is asked by the evil company of the day to test a series of mines infected by what appears to be blood from a meteorite (which eventually turns out to be the symbiote Ellie!).

Worried about what to say? Bring your personal worries about transphobia being signed into law, and trans friends being excluded from public spaces. You are a living person who deserves dignity. Remind your MP of that. You will also get guidance and brochures from Trans Solidarity Alliance that outlines our demands. This is mine from last year.

Money issues? Trans Solidarity Alliance provides a travel bursary that you can sign up for via the link.

Got a refusal or no response from your MP?  Come anyway! You can request a same-day appointment with your MP through a process called greencarding. They will come and see you if they’re already in Parliament. Even if they don’t, they’re made acutely aware of your cause because you showed up in person. This is my greencard from last year.

Here is the EHRC Code of Practice in full. It's a tough read, but some highlights are:

Organisations can’t provide trans-inclusive, single-sex services, or they risk being sued for discrimination. e.g. domestic violence support for women including trans women, men’s rugby group including trans men (12.68).

Trans people will have nowhere safe to pee. If you’re a trans man, businesses can't allow you to pee in the men's, and you can also be ejected from women’s bathrooms if you’re perceived as a man. Vice versa for trans women. EHRC suggests a ‘third space’ bathroom, which is discriminatory and unworkable for most businesses. (13.130-133)

Sports organisations must exclude trans people from single-sex competitions (13.73).  A women’s only sports competition must exclude trans women because of their biological advantage or face potential lawsuits (13.74), but a trans man who has undergone testosterone treatment can also be excluded based on fairness rules (13.81).

Trans women are stripped of the legal definition of ‘lesbian’, and therefore no longer have legal protections if they’re discriminated against on the basis of sexual orientation. (2.50, 2.92).

Here is the Good Law Project's better explanation of the EHRC Code.
