As another gay man, I wholeheartedly agree. The idea of the rainbow was that it represented the full spectrum of humanity and created a cohesive whole of all of us. When Baker originally designed it, it had pink in it to represent sex. That stripe was removed due to a shortage of pink fabric when production ramped up, but Baker has repeatedly pushed to get it included back in. I really wish we'd have done that. The current iterations of the progress flag, social justice flag, and "new pride flag" destroy that unity idea. The dichotomy of the shapes provide a message of tension and individualism which really seems counter to the pride movement. I really struggle with it, because I love the progress it represents, but hate the tone-deaf messaging.
On the topic of Disney and the wall....We've come a long way since companies were afraid to be associated with something 'gay'. Disney has made some missteps in their support over the years and actions like this are a good gesture towards showing they mean to stand by their support. It's very public and photos of the wall will generate a lot of discussion around the company and LGBTQ rights, both good and bad. It would have been all too easy for them to not do this and avoid additional news or press all together.
