GLAAD’s Accelerating Acceptance is the most comprehensive survey we have to determine changes in public sentiment about LGBTQ+ acceptance. It’s literally what I cite when writing research papers about queer issues. The difference is absolutely believable, and they validated the results with sampling bias in mind. There is no reason for you to cast doubt on the result like this, and it reads as disengenuine for you to do so.
Also, you don’t get to decide what queer lives deserve to be in articles about LGBTQ+ people. Thankfully.
