Question around Halal meat being used in the UK

So he recently just watched probably the most disgusting documentary where it was undercover people showing what was going on in some slaughter houses in England.

What I seen actually made me feel physically sick and upset tbh. In the documentary they were breaking multiple laws and not keeping it within the correct procedure for Halal.

I then wondered how often I actually eat halal meat, thinking I probably wouldn’t be since I assumed it would be surely advertised. So I rang pretty much all the local takeaways and out of the 10 I called 8 of them came back and said they used halal supplied meat. I then called the butchers and they were the same.

Now I’m not saying I’m gonna stop eating this meat but I’m actually like a bit confused since I’m not a Muslim and after seeing that documentary I don’t see why I should have to eat meat that is halal. Obviously you are gonna say well shouldn’t I just ask first, but should it not be something you order specifically?

So basically does anyone else kinda have a problem with this? Did you guys know that we are eating halal meat? This isn’t some “anti immigration” and “white nationalist” thing I’m genuinely just wondering if you guys knew this is what we are eating?

Please no hate this is not at all me being racist whatsoever just genuinely asking
