My problem with the way you are judging is not that you don't have a right to judge what someone says. But you haven't asked them to clarify what they mean.
On the topic of the Trinity, I would agree that they are too generic, but I see nothing to indicate that they hold to the Trinity in a false sense.

The e-mail from them states that if I have something in regards to their statement of faith that needs clarifying, they would try to do so. Please avail yourself to this.

I know enough about them, to know that I would not support them.
