I just got blocked by a user for the first time. I found out because I was told I was silenced on another post by them that I encountered; a post which I found interesting, I still shared the post, it was worth sharing. All I did was try to point out their misunderstanding of an article. Can I ask if this is normal and if I have somehow violated a community rule? Sorry to take up your time, but you are my first encounter and a lifeline to the culture here. It wasn't my intention to drive the user off, nor insult them, it was quite an angry response I received. Any pointers?
