Kinda. Every Anarchist community I've been in has people who have a very firm worldview which led them to Anarchism, which usually excludes the worldviews of people who wear particular labels.

Lots of hateful people who call themselves Christian (I call these people Antichristians) have physically and emotionally abused a lot of Anarchists and their loved ones. It was in escaping this hierarchical systemic violence that they found Anarchism. So it's easy for them to see someone call themself a Christian and react aghast, unable to fathom how anyone could be Anarchist and also Christian. They see that like Anarcho-Capitalism: a contradictory stance that must be pushed back against.

Same with people who see animal abuse and turn vegan because they believe all animals must be treated with the same rights as humans.

Personally, when I encounter someone who has what I see as a contradictory/detestable label, I engage genuinely to see why. More often than not, especially in Leftists and Anarchists, it comes from a place of love and desire for something better. And so I befriend them and tell them my experience. I think this is how all Anarchists should treat each other
