I know Althusser (*caveat*), but his insight that there is nothing outside of ideology (which for him is actions that support power, not beliefs) is undervalued. I'm so tired of obviously fascist patriarchal oppressors telling us they're "critical thinkers not ideologues" when they obviously do everything to uphold power as it is. You can't step outside of ideology without stepping into another ideological system. Better to know what system you are promoting rather than "unwittingly" back evil.
