In youth I (like every other teenage boy) unconsciously assimilated misogynistic ideas that were imprinted on me by our culture. Think a rural background with socially conservative working class people. I was a teenager in the era of lads mags, 1990s, pre internet. Access to porn was nothing like today, but the message coming from the media (FHM etc) was implicitly that women existed to service men one way or the other. The route up for female pop stars/presenters was basically, kids TV, lads mag shoots in bikinis, basically trading on female bodies and the expectation that they were a commodity for heterosexual male consumption (I see it now as promotion of a madonna/whore duality as being the perfect women for a man). I went to Uni, horizons broadened, and over time I saw the issue and attempted to change myself. I've thought about this a lot as things seem worse now with turbo charged access to porn and MRAs with huge international followings on social media.
So on to my question, can straight men be feminists or at best, are we only ever active non-misogynists swimming against the tide because of the culture we live in and the assumptions imprinted on most of us in youth?
