Learn English – How to reword “cross-gender” so it doesn’t sound like I’m talking about transgenders

Ze and hir have been around for some time, although they haven't gained much traction in the cis community. There're more listed here: http://en.wikipedia.org/wiki/Gender-neutral_pronoun#Modern_solutions

The sentence

[1.] "I'm going to be talking about...."

has a different meaning from

[2.] "I'm going to talk about..."

[1] and [2] differ in aspect (i.e. the internal temporal structure of the event). In [1] the speaker is focussing on the talking as an ongoing (continuous) event, whereas in [2] the focus is on the talking as a single, whole event.

Both forms are correct, and refer to the event in different ways. You could change from one to the other but you'd be talking in a slightly different way about the event.
