The responses I get from people are the worst

I was SA‘d last year by a close friend of mine. He borderline stalked me after and it’s destroyed my trust in others and myself.
I don’t usually talk to potential partners about what happened to me. I’ll mention it so they know, but I don’t like to give details. Something came over me last night and I gave more context than I usually would to a guy I met up with. He actually laughed at me and said that my friend really pulled one over on me. He was acting like it was a practical joke and that I had been fooled. He then told me any guy would take advantage of a situation like the one I was in with my friend. He acted like my rapist was just so much smarter than me and that it was too easy for him to hurt me.
I know that’s an unacceptable way to talk to people, but I wonder if he’s right. I already blame myself so much for what happened. Maybe I was an easy victim.
