Well, first, I didn't... Michael Che did. That being said, Boston doesn't have the best record on race relations, even being a solid blue city. There were riots over desegregation bussing in the 70s, for example and there was a long history of de facto segregation in the city:
And you know it's perfectly acceptable for people to constantly harp on the racism of the south, where I live. In a black majority city. So I know what it's like to be constantly called racist, backwards, and ignorant based solely on where I live.
I have family from MA (Springfield) and I was born in Concord MA. I also have an Arab friend who lives in Boston and tells me of racism he's seen and at times experiences there.
I didn't call you racist, because I don't think you are. But when we talk about American racism, no place has a clean record, no where is free of a racist past or even present.
