I was bullied out of r/Czech

I've been reading r/Czech for about a year and I wanted to post something for the first time, So I just made a little post "Discussion about AI - Discuss about AI, I don'tj like it, but I wanna see what others thing about it"

Gave it the discussion flair and posted it.

Within 10 mins I got so many insults about how it was a low effort post and how I am just trying to stir up anger or whatever

I genuinely can't tell if I did something wrong or if This is just redditors being redditors.

I deleted the post cause I am somewhat sensitive but I genuinely want to know what I did wrong
