Sentence:  ... a panel of teenagers of LGBT parents ... voiced concern about what they called "<WSD>heterophobia</WSD>"—they wished their parents weren't so negative and distrusting of straight people. Even suggesting that <WSD>heterophobia</WSD> exists for these children understandably evokes angry and skeptical responses because homo-hostile people have used the same word to support a bogus claim that gay rights discrimination against heterosexuals. 
Meaning of the word marked with <WSD> tags:  Fear or resentment of heterosexuals or heterosexuality.
