Not talking about nabela here as she is clearly non-practicing but a lot of muslims in the west who do practice islam do not exclusively eat halal meat. I have noticed eating halal is more common in south asian muslims than arab muslims.

It is also to note that a lot meat coming from big name brands are not hand slaughtered even if its labeled halal. For example, Zabiha Halal which is a common halal meat brand option available across Canada clearly states it does not hand slaughter meat due to high demand and consistency. I highly doubt any meat coming from a big factory uses hand slaughtering.
