Given the clear relationship of corrupt influence in our government by Google (feel free to try and "debunk" this one, please), can you not accept that it is not just reasonable, but prudent to be skeptical of Google's search ranking motives?
I mean, your employer has literally actively gotten involved in overthrowing governments in collaboration with Hillary: http://www.msn.com/en-us/news/other/google-built-tech-to-sup...
I personally am generally hesitant to factually state "Google is manipulating search results in favor of Hillary Clinton", because, as you said, I don't see conclusive evidence. But acting like people are wrong to be suspicious is not much better. If I were to make an educated guess as to whether or not they are, I'd be inclined to guess that they are. You work for a company that makes Comcast look positively cuddly by comparison.
The fact that some bad articles used bad evidence does not prove Google is not manipulating search results, it's merely the http://rationalwiki.org/wiki/Fallacy_fallacy at work.
