Discussing history

So I work as a server bartender, and quite a lot of my customers are secular Jews. It will come up in conversation, and I’ll usually tell them that I’m a bit of a history buff, and know a fair bit about Jewish history. I’ll begin telling them some of what I know, and they seem impressed with the accurate rendition I give them. For me, it makes for enjoyable conversation.

My question is, would you be uncomfortable at all if a bartender struck up a conversation with you about Jewish history - granted that you have mentioned your identity ?
