"Dreamers" are protected because they came to the United States through no decision of their own. They should not be punished for something they had no say in, and especially should not be punished de facto after having been in the US and established their lives. Threatening and intimidating young immigrants, making them fee unwelcome in the country they call home, is exactly what creates the "criminals" that Trump wants so badly to get rid of. They are innocent and hardworking young people that will contribute much to the country they love. Give them reason to continue loving it.
