Martian,  you don't have to worry about Conservapedia,  I just went there and it has a big American flag on it's home page.  Therefore it doesn't represent like Wikipedia does.  It's just for American issues.
Phew!

oh,  i did  a little test.  I entered "dune" into both wiki & conserva pedia  and received quite a different result.   While both were wrong (nothing about Frank Herbert!!!) one had a much deeper approach to the subject matter.  See for your self:
Conservapedia:
Dune - Conservapedia
A dune is a low hill of drifted sand in coastal areas that can be bare or covered with vegetation.[1]
