@Buff - I just used environmentalist as a random analogy, so the details you mentioned didn't even matter in my head.
Why would you even want to identify as a feminist vs just being egalitarian then? If all you wanted was to be seen as someone who treats people equally, why adopt a really loaded term that has way more range in meaning than you ascribe to it? As Kraco said, feminism is not just gender egalitarianism.
Also, the goalpost is still far from being passed even in North America and Australia. The pay gap is still there, and there are still a lot of harassment and power abuse against women (i.e. Ryll's post about hepeating). There's still a lot to do, and saying that there isn't is actually contradictory to being a feminist.
Just saying you support something without, say, donating to movements or actively informing people of the existing disparity isn't exactly supporting it IMO. But that all boils down to the semantics of "support" so there's really nothing to discuss anymore.
I'm not saying I myself will do anything, well, because I'm not a feminist.
