Yeah I think that is the bottom line. I am straight as a ruler and absolutely do not give a flying fuck who has sex with who, it's not my business and I cannot imagine being threatened by it, as long as it's not me why would I care? If you are threatened by the existence of people who love other people there is something deeply wrong.

Pride is literally one of the seven deadly sins, I'd think Christians would want to avoid it.

On the flag design, I think it makes sense, designed by straight guys and looks like it was designed by straight guys. People would get suspicious if it looked fabulous. I do actually kinda like those symbols - they are old, from the 1700s, used originally for describing plants so there is one for hermaphrodite as well. One of my kids is a geneticist and their charts use a triangle for men & circle for women, the arrow and cross ones are better designs IMO.
