The statement that is NOT a common incentive for white Americans to journey westward along the Oregon Trail is, "Advocates for slavery wanted to create slave-owning communities in Oregon so that it could become a slave state."
This is because one of the major reasons why the White settlers left for Oregon during the Oregon Trail was to have the opportunity to live independently in the mountains, fur-trapping, trading, and scouting.
Other reasons why the White settlers left for Oregon include the following:
To move away from current urban capitalism, social inequality, or religious persecution on the East Coast.
To preach Protestant Christianity to the Native Americans of the Northwest.
Hence, in this case, it is concluded that among all the reasons the white Americans journey westward along the Oregon Trail, to create slave communities is not one of them.
