Since when did 'ideology' as a word become undesirable. Specific ideaologies may have unpleasant outcomes but an ideology of itself is not 'wrong'. The use to which it is put may be unwelcome however.

Defining "ideology'

1. A systematic body of ideas underlying a social, political or cultural programme.
2.a manner of thinking characteristic of an individual, group or culture.

Nothing to be scared of or to condemn in that definition I think.

Of course it is possible to pursue one's interests without an defined ideology. But most of us are enculturated (brain-washed if you prefer) to behave according to the ideology of our society. That way we get along wIth each other, as we all make assumptions of response and behaviour according to the society in whch we live.

The ultimate irony of course would be that in fact by living without an ideology you would really be living with the ideology of no ideology.
