The white invaders of Indian lands introduced Christianity to those lands.
They had to murder a lot of the Indians to do so but I'm sure that, along with the rapes, murdering Indian children and so on, were entirely justified.
Here is the abridged version.
The expansion of europeans into the Americas was different than muslim invasions (not that you would be interested in truth). The Indians were not easily oppressed, and won many battles. The Spanish, fresh from Moorish invasions and techniques, tried the oppression of the Indians in the Caribbean, only to discover the Indians would run into the jungle when they tried to enslave them. The Spanish then turned to the most ruthless peoples they knew of: the muslims, to buy African slaves (that muslims and other Africans had kidnapped/conquered) to farm tropical and semi-tropical crops. The Indians went into the jungles and tried to evade the Spanish. On the Continents (North and South America), the Spanish used superstitious beliefs or war to deal with the Indians. The areas settled by the Spanish were either thru cooperation with the Indians or conquerring them.
When the English came to North America, they first settled with cooperation of the Indians (if it wasn't for the assistance of the Indians, many more English would have died). Once word got back to England that the Indians were "friendly" and that there was plenty of room, the English that were being persecuted for their religious beliefs (sound familiar, one who belongs to the persecutors?) volunteered to settle in this distance wilderness. Many of these religious groups set out to be cooperative with the Indian populations and befriend them. They were set onto distant shores with provisions carried with them. That was it. There were implications that the ships might return at some point in the future, but there were no guarentees. Most of these religious groups used morals to deal with the Indians and establish trade and friendly relationships with them. Using "Christian" morals, they gained the Indians' trust where many Indians lived in or close to these communities.
Once the "Christians" established communities, others followed. The French traveled the rivers for hundreds (even thousands of miles). They made trading posts where rivers met and the Indians allowed it (they were outnumbered greatly). The British and the French politicians used military and ruthless men to battle over territiories. Both militaries taught the Indians some terrible torture methods. Both militaries tried to take territory by force and did. They gave "favorites" territory; in many cases, the favorites were ruthless, power hungry men that held little with any religion. Some of these men cared little for Indians or their own countrymen. They killed or had people killed that interferred with any threats to their territory.
It was after this that the English (and the other small populations) declared independence. The "British gov't" was causing problems with the Indian populations, the French, and the Spanish), and taxing the "colonists" for the trouble.
The most famous Indian problems came after the country was settled in the east, and the western expansion started. The "barons" (cattle, railroad, mining, timber) were largely responsible for using greed over consideration to expand kingoms (wanted to be) into the western territiories. The US gov't was manipulated to support them.
Let' compare that to islam invasion:
America: less than 150 years of expansion
Islam: going on 1500 years of expansion
America: trying to work with Indians (now) and giving support to assist Indian reservations
Islam: still trying to murder, subjugate, or convert
America: no terrorist attacks on Indians in decades
Islam: terrorist attacks, daily
America: Indians can worship as they choose with equal rights under the law
Islam: no equal rights under the law or Shariah
America: no walls around homes because people respect each other's freedoms
Islam: if you want it tomorrow, build a wall around it
America: children are cherished and laws are made to protect children, specifically
Islam: children are molested and raped, using the quran as an excuse
You were saying?
Islam is a system that promotes deceit, destruction, death, decay and dust. Christianity promotes a moral society where each person is respected as a product of the Lord. In every instance where Shariah is practiced, people are suffering, terribly. In every instance where Christianity is practiced, people are productive, compassionate, considerate, and educate their children encouraging truth.
