I'll just let Duc Nguyen say it from the article in the OC Register.
"As Vietnamese Americans, I feel we have a moral responsibility to help these people...Others helped us when we were in that situation. Now it is time to pay it forward.”
On the #ICareBecause Campaign
"The concept behind Nguyen’s campaign is to encourage people to post short videos of themselves saying, “I care because…” and declaring why they care about today’s Syrian refugees. They also can write it on Facebook or Twitter with the hashtag '#ICareBecause.'"
Here's video from earlier this month with Duc Nguyen, Bao Nguyen, and Kieu Chinh. among many others.
