Probably because the "material" is generated faster than anyone could possibly analyze it, which is why there are so many variants of the conspiracy theory floating around and why more seem to appear with each passing day.
"think for yourself"
Sure, let's start with, "Does this seem realistic?" If not, let's try, "Is there extraordinary evidence for these extraordinary claims?" Thus far the answer is "no, not even close" and the entire thing looks like a desperate attempt on the part of Trump's supporters to deny the plainly obvious fact that the man is an inept moron with deep insecurities and no conscience.
(Edit: the first thing I saw on website you provided was an assertion that the DNC logo looks like the satanic baphomet symbol. I do not even see what can be properly debunked there -- it is an opinion and there is no actual conclusion to be drawn even if the logo looked kind of like baphomet. I could claim that Trump's left eye looks like the meta key on an old Lisp machine keyboard, and demand that you debunk my claim.)
