When you watch a movie, you either watch the whole thing, or you misjudge it. Same goes for a song, or a comedy special, or anything.
So, if someone presents a clip of a movie, out of context, without additional commentary, what do you think is going to happen??
I think whats going to happen is exactly whats happening in this very thread. That does not mean the author or the work itself is transphobic because its presented out of context of his other works, and his personal beliefs. It's still NOT GOOD that something on its own appears the way that it does to cause this kind of reaction, but that doesn't mean it simply is transphobic because you don't like it.
