Your summary of the Knights Templar seems reasonable enough, its the comparisons you make to the so called knights of Gondor that are the problem.

Gondor had a small number of cavalry who could be referred to as knights. There are several mentions of knights in the books, including King Eärnur who rode to Minas Morgul with a small company of knights to answer the challenge of the Lord of the Nazgûl.
I think it would be helpful to let us know who you're talking about before we decide if we believe you know what you're talking about.
Regardless, you state that Tolkien used occult symbology, certainly the ancient Númenorians, under the influence of Sauron, were heavily into the darker side of religion, but give us some examples of how third age Gondorians were doing likewise.
A large part of the problem with your credibility is you've plucked first century Romans, middle-age Normans, Anglo-Saxons, ancient Egyptians and many others and tried to lump them all into the same culture during the same era.
I know Tolkien borrowed from many different sources to create his fantasy world, but not in the way your trying to do. The problem as others have said is that your "theories" have more to do with how you'd like the world of Middle-earth to look than the way Tolkien intended it to look.
