Question

i said "some" for a reason, i know not all of them are that, however my opinions on this subject are just that, opinions, which is why i refrain from saying anything else.

and in the end, i think this whole thread is down to personal opinion, isn't it?

The original question comes down to opinion, yes.
Whether or not personality is entirely defined by tendency to initiate/a desire for control is not a matter of opinion.

Wait, what?! Chaz bono has a pineappleing BEARD. How is he pre-op!? Does he drink bull semen every hour, on the hour?

He has a beard for the same reason older women can start growing "beards".
He's has more testosterone than a "normal" female body.

And I guess I should rephrase the question to be a little more clear because one sexual encounter does not make anyone anything. But would the aforementioned sexual encounter be considered lesbian. I'm assuming Eos said yes but I feel like he over-simplified it and and Viaje... as usual... over-stated it.

I guarantee you that I didn't exaggerate a thing.
Did I go into more detail than necessary? Possibly, but I prefer covering my bases.

Anyway, the answer that those who specialize in gender studies will give you is the one Eos gave:
Regardless of state of transition, the transgender person would be considered whatever gender they identify as.
So, in the scenario you gave, it'd be considered a heterosexual interaction.

However, I personally don't see this as precluding certain activities in this interaction as being considered homosexual acts.
For example, if the cisgender female tried to answer the famous question presented to us by Lil Kim and Sisqo, I'd consider that to be a homosexual act.
