Do you wash your cast iron cookware?

I keep hearing this persistent rumor that using soap to wash your cast iron is bad. Supposedly it removes the “seasoning.” However, I just don’t buy that and I have always washed my cast iron in soap water. After it is completely dry I reoil it.
It has never caused a problem with me.
You guys know that I’m not a germaphobe but to not wash the dishes just seems gross.
Also, Here is an article that agrees with my thoughts.
So, what are yours?
