What is Target? It is a business. A major one. Their goal is to make a profit. Include the lgbtq community and make more profit. When the larger non lgbtq community says screw that then Target loses more profit than they would have made including advertising for the lgbtq community. So they go neutral to recover their profits.
Nobody is trying to "erase them". What people don't want is anyone telling them that their kids will be a part of the lgbtq society be it in school, in stores, in public, whether they like it or not. Now it has grown to being in everyone's face all the time and the narrative is if you don't like it you are a hatemonger. It's bullshit.
Be ghey, be proud of it but like religion, don't force your personal views onto others. Just because you choose to be a way does not mean you get to force others to be a part of your choice. Want to make the world a better place, be a part of your kids lives and raise them to have some common sense. If they want to be like Rob and be into guys when they become an adult, fine, if they want to scissor gashes... fine. Let them make the choice after they become adults or with guidance if they make the choice earlier in life. Like after puberty.
