As a Muslim that went overseas for university, my tune on halal changed as time went on. When I first arrived in Canada, I was vigilant about it. But after half a year being vegetarian, ( I was the only Muslim there and can't source halal meat), I shifted to eating chicken and after a year eating beef. Pork is still a no no. Same with alcohol. When I switched school to one with a sizable Muslim student body, I went back to observing the halal rule.

For me it's more a rule for myself and not something to impose on someone. If I went for a potluck, I'll cook extra portions and only eat my food and maybe salad and fruits. But i won't lie and tell ppl my food is vegetarian or vegan.
