The conversation started with discussing the lack of assimilation that occurs when you mass relocate people that grew up in one country with a set of values and culture, and drop them in another country with entirely different cultures and values.That's not where it started. The original meaning of dreamers, regardless of how it's used today, referred to children brought here by their illegal entry parents who have grown into adults here. That's whom I refer to.
Agree it's not the best start. But for many/most, it's the lesser evil. Doesn't make you a permanently bad actor.
Dreamers, as you stated, were babies/small children when they were brought to this country. They grew up here, and naturally would have adopted our culture, values, and identity as Americans. This is why the Dreamers debate is so complicated, because those kids (now adults) for all intents and purposes, grew up as Americans.
