I think a lot of homophobes and transphobes don't just feel hatred toward queer people, but they genuinely fear us in an almost literal sense, and so they assume the inverse is true for gay and trans people.
I think that's why you have so many cishet people who smugly say that they're going to make queer people angry, afraid, "triggered" by displays of heterosexuality and/or displays of traditional gender - they think we aren't used to living in a cishet world, that we fear cishet people for their identities as much as they fear us for ours.
