The failures of third-wave feminist wrt industrial exploitation of women & the manifest inadequacies of second-wave feminism wrt class/race/the arrangement of exploitation as a base are how I found Marxism. That said, I would probably categorise ‘anti-feminism’ as a reactionary mentality different to being critical of a particular doctrine of feminist thought - even though ‘feminism’ without description is a meaningless word.

I appreciate you bringing this up and moving the conversation forward about what is often surprisingly contentious for Marxists about feminism, though (the status of prostitution) - it’s important for Marxists to establish a proper line on women’s rights (broadly speaking) and not merely mimic liberals on issues that they may not be informed about. The stance you espouse should be utterly uncontroversial.

Another thing that comes to mind as a practical example for Marxists online is the recruitment tactics of OnlyFans and the proliferation of pro-OnlyFans discourse in sites frequented by teenagers and marginalised women.
