No gay, only queer

Meanwhile in HBO, they play the movie “What Women Want”.

……..
Lola (audio): “You’re totally and completely gay!” (Subtitle: You’re totally and completely queer!)

Nick (audio): “Yes, I am gay”. (Subtitle: Yes, I am queer.)

Lola (audio): “How gay?” (Subtitle: How queer?)

Nick (audio): “I’m as gay as it gets”. (Subtitle: I’m as queer as it gets.)
……..

I’ve seen the subtitles showing ‘crap’ for ‘shit’ or ‘f**k’, but what’s wrong with the use of word ‘gay’? Even Pope Francis has said the word in one of his interviews.
