Why being a female into rp sucks

I should’ve seen it as a red flag the moment they wouldn’t say the exact post. But I gave benefit of the doubt and thought “maybe because they’re new they’re not sure how to respond.” So I continued the conversation. I felt that it was going into an ERP direction, which I don’t solely do plots like that. They didn’t speak English either (that’s fine), I only asked because of grammar. They didn’t know the terms I was mentioning and reacted badly when I said it wasn’t a smut based rp… They also seemed to think roleplaying is all sexual?? Doesn’t make sense, I will from now on not be responding to messages like this.
