Get what? Historical guilt? Feeling guilty about the sins of the past will do absolutely nothing to fix them. Yes, the original European immigrants decimated the local culture and marginalized those who were left. We need to find a ballance in our immigration policy that allows for some continued immigration, but if we allow unfettered "illegal" (note: the native Americans did not have immigration laws at the time because there was not yet a history to teach them the dangers of allowing it to go unchecked, so the term "illegal" is a misnomer) immigration, we will suffer the same fate.
