I'd like to know if using "It" repetitively (for emphasis) in this context is okay grammatically.
TV has become the modern day baby sitter. It is raising our children. It is dictating the cultural narrative and shaping future society. It is raising the bored inattentive child. It is raising the consumer child. It is raising the aggressive child. It is raising the obese child. It is raising the misinformed and complacent child. It is raising the disenchanted child. And what’s more, it is doing all this with our smiling acquiescence.
It
becomes an emphatic term, like a politician slamming his fist on the podium for each sentence. If that's what you're trying to achieve then it works very well.
