I fucking hate that this is political. It shouldn't be. LGBTQ people exist, and depicting them in books is perfectly normal. What's not normal is the psychotic religious freak-out in response.
As an ideology, reactionism is a tradition in right-wing politics; the reactionary stance opposes policies for the social transformation of society. In popular usage, reactionary refers to a strong traditionalist conservative political perspective of a person opposed to social, political, and economic change.
All too normal, unfortunately, but I take your meaning: they're a minority who seek power by drumming up hatred for the vulnerable. Solidarity is the only answer, and it's why they seek to divide us.
