Feel free to call me by any name. I'm your comrade. :)
Humans create words to describe things. Most words are not inherently divisive—universalists recognize the divisions that people make, We just don't prioritize them.
When I talk about identitarians, I don't demonize them in the way the worst identitarians demonize the people they consider "other". I recognize that identitarians have priorities that are not mine. So long as their priorities don't harm working people, I'm perfectly content to live and let live.
If you're a Christian, you should recognize Galatians 3:28: "There are neither Jews nor Greeks, slaves nor free people, males nor females." Is the writer being divisive by rejecting the logic of people who essentialize tribe, class, and gender?
I should do a post dedicated to this subject. I have written a bit about it here: https://medium.com/a-universalist-in-an-identitarian-age/two-kinds-of-anti-racists-identitarian-and-universalist-e561251ff6c4
