As somebody pointed out, the LGB2STQ+ acronyms look like WiFi passwords
The '2S' means 'Two Spirit', a term which covers cultures e.g. Polynesian which have a '3rd Gender', usually men who reject masculine stereotypes and are accepted as living their lives as not-men and not-women- so not the same as trans, they don't claim to be women, they just don't want to be stereotypical men. Hence 3rd gender, they are living outside the male/female binary, rather than denying it.
The letter 'I' is sometimes - less so recently - included in 'LGBTQI'.
It stands for 'intersex'. It's not acceptable because 'intersex' isn't a valid term, there are people with DSDs, differences in sexual development, but they are not 'intersex', they are not in-between or both, they are almost always either male with a DSD or female with a DSD. It's a condition, not an identity, so it doesn't belong with LGBTQ etc.
LGB✂T is used to indicate that transgenderism is not the same as sexuality, and T for trans should not be attached to LGB because trans is a different issue.

So WORIADS relates to a landmark decision and a key moment, and arguably the tide turning...
