There is a huge difference between an opinion and a false teaching.
Here is a potential opportunity for theists and atheists/agnostics to "get along".
It's simple really. Everyone, even Perry, is obviously allowed their personal beliefs. They are entitled to their opinions and freedom to worship. (and the opposite being true, atheists do not have to worship or to have religious precepts forced upon them as the law of the land)
We on this board do well to realize that people likely aren't going to change their stripes too much. The best that can be hoped for is a bit of honesty. An example statement would be
Theist: "Yes, I believe in an invisible being, I worship him and it adds great meaning in my life. I do not have answers to all logical questions for my beliefs, but choose to worship still thanks to my faith. I wouldn't expect others to believe as I do unless they were so inclined, and I understand the reasons why." (I guess the understanding part would be the rub there wouldn't it?)
Atheist: "I see no evidence of God as he is presented traditionally. I allow that most of the world does believe in a supernatural power, and I respect their right to believe this. As I ask logical and reasonable questions and do not get the answers to satisfy the logic, I am content to allow others their opinions, even as we continue to discuss the matter from various points of view."
Atheists do not teach doctrine. They merely point out the obvious.
It would be helpful for some theists to do the same.
For the record, I am rather empathetic to theists on this one. I think at this point in human evolution, most of us need some kind of personal belief system that gives meaning and purpose to life. The challenge is to realize that your personal beliefs, which are at their core, your opinions, are not proveable by any known measure, esp when compared to the hundreds of thousands of competing belief systems that exist on planet Earth at this moment.
Such simple math (i.e. the sheer amount of belief systems) should humble the most ardent theist. Believe as you will, but don't argue to strongly for what at best can be argued to a draw, due to the same amount of evidence that is in existence for all belief systems in the world.
(re read my last sentence a couple of times, it makes sense. Trust me. )
