Well at the very least, I read on the wiki that any diplomatic action raises whiteman so I could just ask for and cancel military access. I think raising it will raise the chance of accepting.
No that is not true, only wars with non-Americans and trading in non-American CoTs will increase the whiteman value. I do not think whiteman has anything to do with the AI accepting trading maps. And ideally you want to remove the isloation penalty and whiteman penalties both in the same month.
From the Wiki:
"Initial Values and Changes to Whiteman
In the 1419 scenario, all countries start with a value of zero for their whiteman. (Low whiteman does not affect non-American countries, but if you look in a savefile their value is zero.) When new countries are created, they get the value 100 for whiteman.
For non-American countries, whiteman never changes. For American countries, whiteman increases by one whenever:
they declare war on a non-American country, or join into a war against non-Americans.
they successfully send a merchant to a non-American owned center of trade. "
