It does give more people the chance to eat it though. Besides if you really have a thing against eating halal meat you can ways check the label of signs to see the meat being sold is halal, then not buy it... It doesn't bother me either way so... Just buy your meat from better places if you have issues with finding non halal meat at the moment, as robgmun mentions.
No one is encoraging Islam in the west that I can tell (other than maybe imams and other religious leaders, which like priests and other religious figures is their job). There is a difference between encouragement and ambivalence. You appear to want discouragement/persecution however.
I'm not bringing up Judaism other than to point out specific points. Don't claim to be on the side of animal rights, while ignoring similar practices by other religions (or as mentioned the suffering caused by other parts of the slaughter process).
That said we do see "Jewish" people building huge fences, annexing land from other states, imorisoning hundreds and killing innocent people by bombing schools and hospitals. It's called Israel, a state with a list of resolutions against it as long as your arm (would be longer if the U.S. Didn't have a veto https://en.m.wikipedia.org/wiki/List_of_the_UN_resolutions_concerning_Israel_and_Palestine) . The difference is I don't blame Jewish people for the actions of Israel, just as I don't blame a British or Indonesian Muslim for the actions of Saudi Arabia.
While I agree, much of the problem is now the industrial scale of most abattoirs in the UK now. The transportation of the animals (quite possibly hundreds of miles) and the scale of the penning and forcing the animals into the killing rooms. Unfortunately that's largely a product of the amount of meat needed to feed our population. Good free range farms are less likely to use industrial abattoirs, and more likely to use their own small on site one though.
