The one to blame is the media. Since every thing has become like a product that can be sold to the people. And since they sell the things & people (as in role models such as athletes) that make you want (sometimes NEED) to buy them to be perfect, or to be like them.
They definitely won't advertise a thing that makes you feel more superior or more better (in their point of view of course).
Also, the target of the media is the MAJORITY of the people (in terms of health, culture, religion. ..etc)within their broadcasting area, so they won't even think of the minority (the different & may be a lot more better people).
Well, you said it, it's because they're "different" - that and people are pricks in general and look down on folks who are "different" and outcasts. Takes more determination than I have to do what those athletes do.
The world is not perfect, it is never fair and just. Only the subtle efforts from our side makes the difference.
We can blame the media, the government for the poor state of Paralympics but ultimately we the people who are responsible for this and should start appreciating something that is different...
For me its just not so interesting to watch. I cant really identify, the sport are different and sometimes a bit goofy. I respect the athletes but its not so strange they dont get the big audiences. Even alot of normal sports dont get any attention unless someone from ur specific country is winning in them.
