Yes, God will punish African-American areas in the United States of America, which vote for Democratic politicians, because the Democratic Party officially supports gay marriage, transgender rights, and homosexuality.
Cities, such as Baltimore, that have traditionally voted Democrat are seeing increase in violence, drugs, gang activity, and murder rates.
Just like the increase in violence in Democratic cities like Baltimore is evident to all, violence in other cities which vote Democrat will be seen by all. God will life His hand of protection from African-American Christians and their children who vote for Democratic politicians who support gay marriage, transgender rights, and homosexuality proliferation.
God always punishes those who support the proliferation of sin in society. This is clear in the Bible.
