I don't find her very likable, and personally I don't think you need to be likable to drive societal change. Undoubtedly it helps, but every iconic figure had gross flaws that sceptics, critics and others were all too happy to point out at the time. There's mountains of evidence of that. This idea that a flawed character is an unsuitable leader on a moral cause is a thoroughly modern notion, and while many iconic figures were likable and leveraged that to further their objectives, many of them weren't.
Beyond that, no I don't agree with how you distinguish yourself from her. Principally I disagree with the notion that you "don't have to portray her as bad". You don't portray her as evil, sure, but you portray her as bad in all sorts of ways. And then you use the "I'm not against her, I merely pity her" as cover for that. That pity, and the arguments you use to justify it, are what portray her as bad. The flaws she points out in other people and the flaws you point out in her are different, sure. But what makes them good or bad is simply your definition of it, which of course is always going to weighted in your favour. It's not an objective truth, and it's not a view I share. I think you do very much the same thing, from different positions, for similar reasons. And I don't think there's an issue with that, I just think it's a weird stick to beat her with in that context.
