Some aspects of your religion are worthy of respect, others are not.
Halal slaughter is one of the things which isn't because slitting an animals throat and letting it bleed to death is more cruel than stunning so it is insensate whilst being killed. Although that isn't great either, I accept that. My aunt used to inspect abattoirs as a vet and it turned her into a lifelong vegetarian.
You don't live in a Muslim country so criticism of your methods of slaughter on animal welfare grounds is perfectly acceptable. You are going to have to get used to that, I am afraid.
So if you find criticism of halal slaughter on moral ethical grounds "disrespectful" of your religion that is too bad, sorry. I feel exactly the same way about Kosher food and Judaism, as it goes.
We have moved on from the time the Bible and Koran were written and animal welfare is one of the things these "holy books" written in more primitive epochs don't take account of.
Even Jesus Christ wasn't very nice to the Gadarene Swine...
"And there was there an herd of many swine feeding on the mountain: and they besought him that he would suffer them to enter into them. And he suffered them.
Then went the devils out of the man, and entered into the swine: and the herd ran violently down a steep place into the lake, and were choked."
Luke 8: 32-33.
You can't get away with that kind of stuff nowadays...
