Absolutely it would be, and usually is in my experience. Obviously everyone's experience is different but in the vast majority of feminist spaces I've been in (socially, women's studies classes at school, etc), there's been a lot of discussion about how sexism harms men, and the shame surrounding male rape comes up a lot. One of my profs was dismissive of male rape and I was glad to see a great number of students stand up to them about it. In my perfect world, nobody should be ashamed or scared to report their rape, and it should be treated seriously in everyone's case.
