That doesn't make them feminists. It means they're trying out ways of living their life and thinking that have been provided for them by feminist beliefs because they feel it's a better current option than the alternative.

But id that option wasn't available, they wouldn't fight for it. And if the new option didn't work out for them or deliver "as promised", they'll either go back to whatever was before or find some other ideology to follow.

Most people are wishy washy like that. Women are no different than men in this regard. They're looking tonadvantage themselves first and foremost and really don't give much of a fuck about belief systems, ideologies, the greater good, social progress, or any of that.
