The point I'm trying to make here is that "It's hard to explain but his intention in much of his writing was coded. He would consistently use certain keywords and phrases to make certain associations and when you follow through the logic it becomes very sinister" does not, in fact, outline an argument. It merely asserts that "much of his writing" is "sinister" without making any argument for why - and you've now once again claimed "his writing is full of associations" ... without ever having named such an association.
There's no requirement to make such an argument, of course, but if you're simply going to state your beliefs with zero explanation then it would be preferable if you were up front about having chosen to do so rather than claim to have made an argument where none exists.
