As with many other communities - the vegan community is not homogeneous. Like I said before - yes there are some people within this community who are dogmatic, but that doesn't mean veganism is dogmatic.
The core principle of veganism is not wanting to harm non-human sentient beings and generally not wanting to destroy our biosphere.
So if someone strives to live by those principles, but still has to use products that contain animal products, e.g. if you need to take medication that contains gelatin or similar and there are no alternatives then it's OK - it's not dogmatic.
Further down this article there are various other examples: https://veganfta.com/2022/11/23/practicable-veganism/
Or here is another article talking about this: https://veganstrategist.org/2017/09/13/beware-vegan-dogma/ - this person wrote a book called "How to Create a Vegan World: a Pragmatic Approach".
The goals is to get rid of animal factory farming and the destruction of our biosphere. Dogmatism isn't going to get us there.
If people don't even know and understand terms and philosophies/ideologies then there is nothing that can be discussed.
In any case, best wishes for the new year.
