This "our project is open source, feel free to submit a patch" dismissal is so passive aggressive. If you mean "fuck you," then just say "fuck you."
That said, you shouldn't be saying "fuck you" in the first place: it's rude, it contributes to bad vibes in the OSS community, and it hurts you more than anybody. Try instead something like: "I'm having trouble understanding your argument, do you mind explaining in more depth in an email?" Even if you're dealing with a troll, this is still the best strategy.
