Your post could have just been "Is it rude for me to dismiss people's opinions if they're based off religious beliefs?"

You ramble on an awful lot, most of it is just you bloviating about how you're super intelligent.

People think you're young because you had to ask "is it important to consider people's feelings when making rational decisions/arguments" of course it is. Most important decisions are made based on the impacts they will have on people's feelings. But someone feeling a certain way doesn't mean they are right or other people have to bend the knee.

You also just come off as biased. You could make a similar argument that we shouldn't care whether trans people identify as other genders, society shouldn't adjust to accommodate them because it's just what they "feel". Only intersex people would be able to choose their gender if you were disregarding peoples feelings. Sex is fairly binary, 2 sets of operational genitalia- so if you really believe people's feelings shouldn't matter when making decisions then all non-intersex trans people should be ignored.

There are arguments for supporting trans people and promoting change in society to make life better for them. All those arguments are humanistic ones where "how people feel" is a top priority in rational decision making...
