Well, you see, rather than directly engaging the things they actually said you, instead, chose to ask them about things they didn't say and wanting proof of things they never claimed, essentially giving them unrelated homework for a comment you seemed unduly suspicious of. They talked about very specific instances of lies.

Fascists are also right wing and the lies they're talking about, per their comment, are the deaths that happened under fascism.

They may not know about all those things you asked but still have knowledge about the things they said.

Hope that helps.
