I myself do not really view “What is to be Done?” as a great beginner work for Marxists, since it mentions a lot of obscure philosophers or groups that a modern audience (with their cursory knowledge of Russian history being from the lips of liberals, or worse, conservatives) would hardly know the context of, and I am reading a version that has notes on these people!
That is not to say that it is not an influential or essential work of Lenin (I think it might be up there with “Imperialism, the Highest Stage of Capitalism” and “The State and Revolution” in terms of either factor), but one has to be willing to trudge through Russian names that you will likely never hear again.
I get what you’re saying - and I agree that more needs to be done - but more cannot be done until we start treating the issues seriously. That’s the point of “Believe All Women”: it is the beginning, not the end. Violence against women cannot end until it is taken seriously. Even women getting the political power to fight this issue ourselves requires being taken seriously first. There is no emancipation for women from patriarchy at all until the social attitudes - which go far beyond what individuals believe - that mock and patronize women are confronted.
You can apply a similar approach to the working class: if you view workers as stupid, helpless, lazy, or uncivilized (all of which are common classist stereotypes of working class people) then you’re not going to be meaningfully advancing workers’ rights or our emancipation from wage slavery.
Same thing with racism: you have to acknowledge other races as humans before you can end white supremacy.
Etc.
