I understand how this person's responses are frustrating to you, but educating us is no one else's responsibility, and people are allowed to assert that you're wrong. You can choose how to engage with such people, but I mean if you haven't confirmed that you understand the difference between the two types of agreements (I also don't know, no shame there) then instead of insisting that it is someone else's responsibility to educate you, do some legwork on your own.

Or don't, maybe they're just an asshole. But don't demand people do unpaid labour on your behalf.
