It appears to be surprisingly traditional for that neighborhood (I lived there while going to UW).
Did you actually peruse the site you offered? http://www.churchbcc.org/ I clicked on several links. One link connected me to an article on World Vision (that just had to change its course on same sex marriage because of what would be a financial fallout.) Click on the associated links.

We should all be about helping people in poverty. Maybe you have a different definition of liberal church.
