Feminism is defined in most dictionaries as being something along the lines of 'Belief in or advocacy of women's social, political, and economic rights, especially with regard to equality of the sexes' (quote taken from thefreedictionary.com). As far as I can see, striving for equal rights for all genders can only be a good thing, and feminism in general revolves around that view.
Of course, there are some people within the feminist movement that get things wrong, as with any movement. In nakaraan decades, a lot of feminism was mostly focused on white, middle-class, straight, cisgender, able-bodied women and didn't pay an awful lot of attention to women whose problems weren't relevant to that category, and there are some feminists who still aren't quite as inclusive as they should be. There are also some extreme groups such as TERF who are openly transphobic (they believe trans women aren't 'real' women and should be excluded), and I'm pretty sure there's another group that is hateful towards lesbians, bisexual women and non-hetero women in general, on the basis that such women supposedly give feminism a 'bad reputation' (quite what that reputation is supposed to be or what's so bad about it, goodness knows).
However, I'm happy to say that the majority of modern-day, intersectional feminism has progressed significantly, and these days madami feminists recognize that there is so, so much madami to being a woman than only being straight, white, cis, able-bodied etc, that every woman faces oppression in different ways, and that everyone is deserving of equal rights, regardless of their identity. This website happens to do a good job of explaining intersectional feminist issues, in case you're interested;
