Is communist idea of base & superstructural bullshit?

Yesterday I had argument with Cowbee about this here. This seems like hijack of word "base" to support their propaganda like many others Words Which Defy Dictionaries. Base, is always ideology. Sure their so called "base" influence upper ones, but it is not the base. Base is something core, without it the thing cannot function. can human live without ideology? Without right or wrong?

It make sense to base our self on other ideologies but not on ideology of means of production or ownership first.

If you think this is misunderstanding, please explain your argument in simple language without using communist jargons if possible.

I suspect hardcore communists doesn't want to admit flaws instead they blow up dust of words to cover. I also suspect that i can be wrong or half understood the argument or using wrong definition of terms, that's why i am posting here
