I never claimed it was "normal". I know we get more opposing fans than any team other than the Chargers. What I am saying, is "normal" is changing. The days of a stadium, any stadium, being one solid color is over. Did you not see all the blue among the red in Arrowhead last night? Sure, the Giants fans were outnumbered big time, but it was easy to see that they were there in a few thousand.
It is also changing in our stadium over time. It isn't as bad as it used to be. It just isn't. I have sat in our stadiums for almost every game since 1994. You can't tell me I'm not seeing what I am seeing.
