I should say I strongly agree with that.
As everybody else. Write down a paper, send it to your preferred journal, and you'll see what happens. If you have an interesting theory and you fail to share it with the rest of the world, it would be a terrible loss for knowledge. Here on PF you will not be able to get as much attention as you would get from a peer reviewed paper.
Otherwise, you can try to use the Independent Research
subforum to discuss your theory. That could also give you a good step to prepare before trying to publish seriously.
