They should respond that there is no such thing as homosexuality.
Homosexuality, gay, bi-sexual and all the other euphemisms, are all just made up words.
God created us male and female, and we were made for each other.
Sex is for a husband and his wife, and anything outside that marriage relationship is a perversion, all of it bad, some of it worse.
“Homosexuality” is anti-God, anti-evolution, anti-male, anti-female, anti-children, anti-future, anti-Kantian and anti-love.
It all started with the “Playboy Philosophy” snd a sick pervert named Hugh Heffner.
