Meeting my booe's parents on Wednesday, HELP ME!!

So I've been dating this amazing guy named Treyvon for like the past month and a half (August 17th was when we first met. I've mentioned him before right?) Anyway, he asked me if I wanted to meet his parents this Friday and I've never met any of my booe's parents before. I mean I'm a nice girl, I'm respectable, but he thing is...

You know the old southern black guys who hate's everything white who always had some horror story about what some group of teenage white boys did to him when he was younger? Well, guess what his grandfather is who lives with them? :( Not only that, his grandfathers uncle was freaking lynched by a mob of whites before his granddad moved up to NY. So I'm like really, really nervious about that. I mean, I have no clue how to act around his grand father, I'm not sure if Treyvon's mom inherited his hatred for whites (he tells me she didn't so that's a plus) But this sucks. I mean I really like this guy, I want his family to like me, but I'm not about to lie down and apoligize for what a group of people did way before my time, even if it was really, really sucky. Do I tell him I'm just not intrested and not come, or do I suck it up and hope his grand dad act's nice to me. Also, would it be bad to bring choclates and flowers to his parents, or is that more of a guy thing?
