I am a very open minded person - I am accepting of all people, I teach at a school full of kids that are from widely maligned backgrounds - so it upsets me when people's choices are removed. Especially if these choices are roadblocked but unnecessary organisational wank.
I understand that there are people in the world who don't want to read about homosexual characters. That's their right. It's just like I don't want to read about excessively whiny, feminist throwbacks that fall in love with wane vampires that stalk them at night. But hey, that's my choice. Amazon's newest policy is ridiculous.
Imagine being a closeted gay teen who finds some solace and relatability in a novel that addresses homosexuality. Imagine not feeling comfortable entering a bookstore in your small, homophobic town because a) you will be judged and b) they won't be available anyway. So you go to Amazon to find a book with a protagonist that you can relate to, with subject matter you want to read and it's not there. The search function shows that the only texts available are about how not to be who you are because certain titles have been "blacklisted". Imagine that. Removing accessibility and ultimately a platform for "adult" content books is stupid and ultimately bad business - Amazon, have fun with the damage control.
This is why I have posted Jackson Pearce's vid - she explains it much better than I ever could.
