(Note: I really don't like the character either but it is being taken way out of context)

​

There is apparently way more context to the character and the show. Mia (the character in this video) isn't meant to be a religious and a good muslim, she's meant to be a very unlikeable character (and judging from all around muslim social media it worked) and the entire show plays off of the cringe-wokeness of our current generation. Even the actor for her felt uncomfortable because they were bringing up religion and knew it was a heavy topic.

"Not that I’ve been aware of. I was actually really self-conscious about it going in. Obviously because I’m playing a diverse character and talking about religion, that was kind of nerve-wracking for me."
"I’m personally not Muslim, and I play a Muslim character, and I know it’s really important to represent that correctly and show respect. It’s hard, because it’s not necessarily a respectful show. I was concerned about that. But I haven’t seen any kind of issues that have come up yet."

Although, during the interview, there was another thing she pointed out when she talked about her religious beliefs and story.

"Just because I’m Muslim and you’re Muslim – we take different things from that, and we follow different rules that suit us. And that’s what the core of that topic in the episode is. That was quite special to me because I really relate to that. I know a lot of people in my age bracket do, too, because the standard of what is acceptable in older generations is not the same now. I think that’s really important. It was really rewarding to do that episode."

She's half Sri-lankan and compares Mia with her experience growing up in her culture as well, which was just that she wasn't allowed to eat with utensils and with her hands instead. Compared to Islam, a religion, that states that alcohol and pork is at least haram (along with Zina with seeing how Mia is a very sexually-active person.) at least she wouldn't have any need to care about wanting to eat/drink foods that are prohibited, but that wasn't the intention of the creators.
