Lmfao, no, if we stopped all immigration in the United States right now, whites would still be a majority in the future.
Hispanic birth rate in the US as of 2013 is 2.15, only about .4 higher than the white fertility rate of 1.75. African Americans have a marginally higher fertility rate of 1.88. Asian immigrants have a LOWER fertility rate.
This isn’t even mentioning the fact that under a country with strict immigration policies, the only Latin Americans able to immigrate to the US would be wealthier ones, who DEFINITELY have a lower birth rate than poor, disease ridden Mexican trash.
Get your head out of your ass. There’s nothing wrong with wanting to preserve one’s heritage and cultural identity.
