or, How I Learned to Stop Worrying and Realize This Assgrab is Delicious
This is entirely a matter of easing mass audiences into the concept. You can't just hammer this through because idealism.I disagree. This is a ludicrous double standard. If a bad guy is blowing stuff up and some dude is like 'please Hulk save my wife' that's cool, but for him to say 'please Hulk save my husband' would be cheap? That's crazy. The world doesn't, like, default to hetrosexuality. My existance in aspects of my life involving hetrosexuals doesn't require me to be intricately woven in.
In your example above, yes, you could have a minor male character turn out to have a husband. But don't tell me they can't treat that sequence with care. Of course they'd have a big meeting about that sequence and decide how to carefully introduce that concept, maybe show that they are a couple in a moment befor or after, consult LGBT experts on whether they feel it is appropriate, etc etc.
Because honestly? Even a little sequence like that could really take people out of the movie, and risk pissing people off, if it comes across as cheap or jarring.
