The Wayland community in general do feel like that it's comprised of a lot of young, immature and cliquey members, which is quite unfortunate since it's an interesting technology.

These attitudes can be seen not only in political topics (such as the one described in the article), but also other stuff in general.

For example, sway once forced users who are using Nvidia gpus to type --my-next-gpu-wont-be-nvidia so that the compositor works properly. It's nothing explicitly offensive, but you can see how their attitudes against "unapproved" outgroups oozes out here.
