Close minded: having or showing rigid opinions or a narrow outlook.

I said I did not like you calling me out on shitposting repeatedly then proceeding to shitpost more than anyone here combined. I then proceeded to explain how my post had thought put into it and did not fit into your half valid definition of "shitposting". I then proceeded to explain how a post under five words could be still deemed relavent, which you took as an excuse.

Please expand on how I'm being close minded
Is it because my posting etiquette does not fit your standards? Please elaborate.
