It fits their agenda for them to allow people to assume that they are talking about children of the same sex who identify as transgender, so that they can frame any objections as bigotry, and the same as homophobia
I do wonder how many times they think that they can do this before we notice 
As if it isn't entirely obvious every time, that people all.if a sudden go from knowing what they are talking about to complete non answers with the desperate seeking of audience participation where said non answers can be drowned out by cheers and claps.
Its the discussion equivalent of ending your story " and it was all a dream". Completely cliche obvious and lazy.
If nothing else the lack of interest and effort should immediately be cause to lose faith in the person and be angry that they have nothing better for their public they are meant to be serving
