" Gay people (and other members of the LGBTQ+ community) are normal humans,"
No, they're not. 1) They make up about 5-8% of the population. 2) Normal humans don't parade in the street with assless chaps and think they NEED an entire month to do it. That isn't normal, no matter how you look at it.
"deserve to be part of the public discourse about love, romance, parenthood and all the rest."
No, they do not deserve children. They deserve each other and to live as not normal adult human beings. They definitely don't deserve to be with children, just as perverts have no business being with children.
And they don't have any business showing off who they prefer to have sex with in the open, especially in front of children. It's disgusting and wrong. Their whole identity is who they prefer sleeping with in bed.
But it isn't homophobic, as I do NOT have an irrational fear of them.
