The truth is that mainstream Hollywood films are not made with LGBTQ audiences in mind at the studio level. The films are made to cater to worldwide audiences including culturally conservative China and countries with far less advancements for the LGBTQ community than Europe or the U.S.
Basically from a statistical accounting standpoint that would be like not catering to the entire state of California in order to sell to an entire country with nearly 2 Billion people in it with a ton of disposable income and a large middle class as opposed to the LGBT millenials who have very little income due to the vanishing wages and middle class of the United States.
People may claim there are more LGBTQ people out there closeted but
unfortunately you can’t market to someone you do not know exists.Film is a business, not a public service, America doesn’t have a grant system unlike other countries. All I can do is encourage you to support smaller LGBT features and perhaps make some content of your own so that years down the line things will improve.
