What does it even mean to "see trans people as valid"? What does it mean to see X group of people as valid or invalid? Honestly, I don't understand this statement.
Looking at your comments here, it's starting to look like you have a singular agenda will just support whatever larger movement best aligns to it without considering the moral or fairness implications. Nothing wrong with that I guess, but that is the antithesis of inclusiveness or ethics.
Why should 'helping other minorities' be exclusionary. Who is this 'other'? Trans people are NOT actively sought by employers - I've personally witness the exact opposite.
Maybe the issue is that people - including those who use religion as a form of control - have forgotten the Golden Rule.
This sounds like you think we need to serialize helping marginalized groups. Was that the intent?
I'm totally okay with that particular poster continuing to focus on the trans community because of their own personal agenda, but pretending that they represent inclusion or fairness is an outright lie at that point.
I have transgender, transsexual, and transvestite friends who I care deeply about. That's absolutely true. I want the world to be more welcoming to them, because I see the disapproval society heaps upon them as sitting at one of those particular intersections of unfair and unnecessary. If you have groups you also care deeply about, feel free to share.
