If the targets were not influential or the title gave out the blog content (e.g.shame on my neighbor for being a Trump supporter), it would be treated like yet another personal rant against Trump. If the post presented comprehensive but complicated political analysis, it would loose a big chunk of the intended audiences. I applaud for Marco's ability to convey his political opinion to big audience through a simple blog post. That said, if you are used to performing critical thinking whenever you read stuff, this post is probably not for you.
This post doesn't give people much constructive material to argue over aside from fueling more potential verbal violence. The same goes for most media political pieces. They are political snacks, cheap to grab and quick to consume, but too many snacks are bad for health, in this case, bad for decision making.
