I haven't engaged directly the OP because my hearing is bad and I can't hear Maeve's speech on the video, but I trust your five-star reviews!
And as I've said before about this wonderful young woman, she lives up to the fearless mythological queen she was named after
However, I have a very direct comment on the motion, 'that this House believes modern LGBTQ+ activism fails its community': there is no LGBTQ+ 'community' - there are three parts to that acronym, the first part referring to one group of people: people who are sexually attracted to people of their own sex; the T part refers to people who believe they can change sex; the third part refers to people with a variety of opinions on the subject of sex
These are separate groups of people with different identities, different histories, different demands, different issues. Some parts of it are actually inimical to other parts - for instance the treatment of lesbians - so it is hard to see a group of people as disparate as the 'LGBTQ+ community' as constituting a community, i.e. 'people having a particular characteristic in common', which is the dictionary definition.
The Dentons Document suggested 'piggybacking' as a strategy for promoting the trans agenda, meaning adding trans rights to existing rights organisations, to capitalise on their successes.
They did this by adding the 'T' to LGB - it started appearing as if summoned by magic, as a fait accompli, and we haven't been able to get rid of it. Yet.
The Dentons Document - a 2019 report which set out to 'to create user-friendly resource for itself, its members and the broader advocacy community for use in campaigning efforts for better gender recognition laws across countries in the Council of Europe'. is available here:

adopting accessible, rights-based gender recognition laws, especially for young people, offering critical lessons for future advocacy
[my underlining.
'LGBTQ' is an artificial construct. It is not a coherent community.
