I feel Koreans are the most evangelical and most socially conservative asian group out there. At least they are the best at indoctrinating it into their kids. Other younger asians are very socially liberal, mostly because they grew up around socially liberal whites in suburbs. Of course I am speaking from a Californian perspective and things are probably very different in Texas.
Asians just pick up on their surroundings for the most part.
The Koreans in my area are generally very religious and are the exact opposite of the typical ideology of Seattle's nonreligious, fiscally conservative suburbs.
