Now I’m. I live in Catalonia but I travel a lot around Spain because of my familiy, I always found very funny that on School they told us that Castañada and Castañera was a tradition of Catalonia but when I traveled to other regions of Spain they also had Castañeras and celebrated castañada.
And that applies for most of traditions. In reality is just normal that we share so much in common, we have been a country for so long.
Every region of Spain tries to take a tradition as theirs as some kind of nationality proudness. But if you travel a bit around you realize that we share so much in common.
I think it depends on the community. All the ppl at sdf.org are pretty cool though. Maybe your instaces is full of annoying people and you only see that in your feed.
