If you feel anyone's opinion that isn't your own is somehow FUD, that's a problem.
For example, you are unlikely to change my viewpoint or opinion on a great number of things, even through well thought-out and concise arguments. I also happen to believe Fox News isn't as terrible as a lot of people like to think (they are, after all, the news network with the most viewership and highest ratings year after year).
Point being, you shouldn't attack individuals because they don't agree with you (or the popular opinion). You should attack their argument.
And clearly someone who's invested enough time into getting 1K+ upvotes isn't a drive-by-night account. I get suspicious when new accounts post that were created on or around when the article was posted, and/or accounts with very long account history but almost no comments and no upvotes (why go 500 days with no comment but now you post?).
