You are twisting the context. You were posting pictures, as If as though you were advocating the pork dishes. I am a strict Muslim, but I am all about personal freedom. If someone was eating shit in front of me, I wouldn't dictate my views on a person. My job as a Muslim would be to advise why eating the shit is not good for you. You on the other hand, were posting pictures that it is an acceptable practice. I'm all about live and let live, but I'd also try to help and better my community.
Cultural and religious sensitivities also play a part. I wouldn't have a picnic on Holi hindu religious festival and serve cow If I invited Hindus. I also wouldn't burn Jesus posters on Easter and invite Christian friends. That's called a dick move. These people served pork curry during the end of Ramdan, and it might have been considered a dick move by the community.
Common sense plays a role here.
In the past few weeks, there have been threads where Hindus were fasting along side Muslims to show solidarity, and that was a postive thing, but regarding this episode, we'd call serving pork curry a dick move. You may say that Muslims were offered alternative options. Well what If the function was not set after Iftaari?
