Author appearances and book talks are usually peaceful and rather tame affairs, where the majority of the audience is fond of the author’s work, and everyone nods in agreement at everything that is said. But that wasn’t the case on June 8, when journalist and author Rachel Hills interviewed Jessica Valenti (inset), author of the new memoir “Sex Object,’’ at the Uforge Gallery in Jamaica Plain. Apparently their discussion on feminism and modern womanhood was so engaging that it raised the ire of one male attendee who ultimately got thrown out.

“Apparently he was muttering some stuff while I was doing my reading,’’ said Valenti, in a telephone interview. “And during the Q&A he said I was giving New York a bad name.’’

Valenti said it’s not the first time she’s been heckled at a book event (it happens quite often) but the former JP resident was surprised that it happened in her old ’hood.

“Despite this one gentleman, it was a wonderful event,’’ she said.?

Valenti also turned to Twitter to vent about the incident.

“My event in Boston tonight was amazing, so many wonderful feminists + 1 old mansplainer who said we have to go back to the ‘good old days,’ ’’ Valenti wrote after the event.

(For those unfamiliar with the term, a “mansplainer’’ is defined as a man who explains something to someone else — typically a woman — “in a manner regarded as condescending or patronizing,’’ according to the Oxford Dictionaries.)

In another tweet, Valenti wrote how she emerged victorious in the end: “Then he got physically removed after getting super nasty. Felt like I won some sort of feminist event bingo.’’
