Not necessarily. I used to hold that view, but that black-white mentality is divisive. And I would argue that anything divisive could be propaganda.
My stance on what I believe has not changed but I have met people that I care about that just don't see what I see and in telling them about my view, I realized I needed more concrete evidences. A lot of what I believe is based on hunches, intuitions and feelings. Not to say these things are not as important, because after all, as a species, we survived on those things for thousands of years.
However, I do care to at least present some concrete into to the people I care to share these info with.
