CAT has been in the news after announcing they would no longer support Boy Scouts because of their bar on gay leaders. UPS took a similar position a few months ago.
Last week, I had a choice in shipping sources for something I ordered...I told them I would not buy from them is they used UPS, so they sent the package with another shipper. I will continue to look for ways to avoid UPS. I will have absolutely no impact on UPS, but maybe there are some others out there.
To answer your question, I believe this signals a fundamental change in the Boy Scouts of America. It is clearly not the organization in which I have been a member for about 50 years. The organization I supported no longer exists.
You sir have a problem, and it's not what shipping company. I don't know you but what if your child was born gay? Would you have posted this message? Would you not love your child unconditionally? Seek help.
