"But it won’t be respectful if, when speaking or writing about me, you call me, as a trans woman, ‘he’ or deny my right to use the facilities society has decided I should have, such as my right to use the bathroom of my affirmed gender should I visit premises under your control? "
No such right exists. The Equality Act 2010 is clear about that via Schedule 3 [Services and public functions: exceptions], Part 7 [Separate, single and concessionary services, etc], sections 26 [Separate services for the sexes], 27 [Single-sex services] and 28 [Gender reassignment]:
