I'm seeing a lot of blogs and Facebook posts generating comments condemning Islam and/or immigrants. So I just thought it might be time to make some things we all know, or should know, clear.
The worst violence ever perpetrated in this country was caused by European immigrants against the original natives of this country.
Second worst violence was started and caused by fellow citizens who decided they didn't want to abide by their own country's laws if it meant giving up their slaves, or initially keeping them but not being able to expand the territory in which that was legal.
So if any one group is going to be generalized as violent, it would have to be first Anglo-Americans and second Southerners, as they caused the most violence ever in our history (and before you send comments, many in my extended clan live in the South and I'm not disparaging Southerners, or Anglos, I'm criticizing those who make generalities based on prejudice, pre-judging a group based on some in that group's actions etc.).
Most deadly "terrorist" attack in the USA before 9/11 was perpetrated by a rightwing "American"—Timothy McVeigh.
All the presidential assassins in our history were American citizens. (One was the son of Polish immigrants, but he himself was "American" and another, Lincoln's assassin, was the son of English immigrants.)
It is also pretty clear the majority of all those who caused all the violence referenced above were Christians, or at least brought up as Christians.
[It also seems clear that most of the death and destruction caused by "our side" in our last three big wars (the little ones as well actually)—i.e. Viet Nam, Afghanistan and Iraq—was caused by "Americans" many of which, most of which in fact, were also Christians.]
That said, whoever causes death and destruction to anything on this planet besides rats, cockroaches and mosquitoes, sorry, I am against.
