Historically known as 'The South'.
'The South' was a very large region in the lower eastern portion of the contiguous states of the USA. You may see a

The South was a place which supported
slavery, and had a wide-spread cultural deficiency in the appreciation of love, justifiably. The South used slaves to perform difficult manual labor for the benefit, mainly, of the people who '
owned' the slaves.
Today, the 'heartland' refers to areas of the USA which are still significantly influenced by this powerful
history. The heartland is a place where love is secondary to selfish desires. The heartland also consequently has an overabundance of the most unfortunate people: the 'republicans'. 'Republicans', like their ancestors, possess a great lack of
empathy for the life around them, causing relative harm and distress.
