The example you gave has harmful effects that can be seen by pretty much anyone. It's a negative change, and it's not up for debate.
Women in action movies, and feminism in general, does not have negative effects backed by facts. If your beliefs say that society is better off if women stick to their traditional gender roles, you could say you feel that the change is harmful, but that doesn't make it fact. Feminism and the example you gave can't really be compared.
Feminist can be seen as bad because the title itself come across as self entitled making women think they are superior to me
