There really isn't much difference at the level of beliefs. Some people believe in immortal souls, some people believe in guardian angels, some believe in paranormal auras, some believe in gender identities. And so on.
The difference comes at the level of society and politics. Generally, and over the years, we have learned to tolerate one another's beliefs. We no longer discriminate against those who believe different things to us. We no longer have laws based on such things as the "real presence" (or absence thereof) or imprison (or worse!) 'blasphemers', 'heretics' or 'unbelievers'.
Our schools no longer tell our children in schools that they have immortal souls or guardian angels etc. Rather we mandate teachers to tell our children, "Some people believe ...".
But, now, believers in this latest metaphysical claptrap, 'gender identity' demand special treatment for themselves and their beliefs. They want belief in gender identity enshrined in law; they want children taught it as fact; and so on.
Of course we should refuse. Believe whatever you like. Worship any god, describe any aura, tell any story you wish. But leave aside our laws, and particularly, our children.
[Oh, and just for the record, there are no such things as guardian angels, paranormal auras, gender identities, omnipotent gods or immortal souls. But I hold no grudge against those of you who believe in such things. Fill your boots; believe what you like. Just leave me and my kids alone.]
