By the way, if we're talking about being discreet, most reasonable members of the LGBTQ+ community don't flaunt their orientation, don't engage in public displays of affection, and so on. They simply love whoever they want, and that's it.
Of course, you can call those who display their "love" publicly by any name you like, but it's precisely because they do so in public, including in front of children, that it can potentially distort a child's mental development (though the age factor should also be considered). However, if people live a normal life together, work/study, care for each other, and generally lead a peaceful life without putting their feelings on display (except perhaps holding hands), then in my opinion, there is no reason to criticize them, as they cause no harm.
