That's where you are wrong. Sherdog is just a place where people feel more free to speak their mind without all of the PC police. With the extreme leftist media/politics, people can't generally speak their mind freely if it is politically incorrect. As an example, consider that Trump got elected despite that anti-Trumpers were WAY more vocal than Trump supporters. "Normal" people have been told to sit down and shut up for decades by "progressive" liberals. For the most part it has worked since every time someone expresses traditional views they are labeled racist, xenophobic, homophobic, deplorable, etc... despite that most of the time those labels are not even true. They are simply tools to push a liberal agenda.
Don't want illegal immigration? Nevermind the effects on our economy/government, you must be racist
Believe that men are naturally stronger and faster than women? Nevermind biology, you are sexist
etc, etc, etc
Beliefs that come easily via observable reality (such as penis/vagina/chromosomes determining your gender) are now "wrong" because someone might be offended.
We now must conform to what someone wants their reality to be, rather than facts.
