I am opinining on what I read, that Heinlein wrote.
I read all of Heinlein I could find. He was a great writer.
But, he had his weaknesses, and they contributed to the current situation we find ourselves in.
Heinlein influenced a lot of people. It is what writers do.
Many things he pushed as factual, were simply his opinion.
On balance, it is hard to say if he helped or harmed the Republic more.
Yes, he was a great writer.
Yes, The Church of All Worlds is a reality.
