This is an odd discussion point, but I am curious if, as a matter of general opinion...
Should people of any race, creed, color, religion, or ideological affiliation be able to buy land anywhere in the world presuming the parcel of land is for sale? This can be done by an individual or organization representing an interested party(s).
This is a simple and hopefully straightforward question. This is not a question of "should land be purchasable?" which is its own interesting debate.
EDIT: As a second point, also answer if its within one parcel of civil territory (I.E. a citizen of a State buying land within their respective State)
