“Kosher,” like “halal” and “organic,” is a label voluntarily attached by a food producer as a branding strategy. It gets slightly complicated because producer groups can and do disagree about, for example, the meaning of “organic.” So they scamper off to an outside authority such as a religious body or government seeking an authoritative ruling on the meaning of the word. But the primary point to make is that this is voluntary, affirmative labelling affixed as a marketing device targeted at a niche buyer to whom that particular quality matters. There is nothing wrong with this.
Bottom line, if you don’t like the idea of GMO’s, you have a simple remedy. Look for the organic label.
OR, PUT IT ON THE BALLOT!
Fair enough about Kosher, halal, etc.
Let me use a different example:
Now, let say you have a passion of not buying products made in countries other than America or ones that have no child labor laws. However the label showing that the product was “Made in China” is not required (The product was made prior to The Textile Fiber Products Identification Act). You want to buy only American made items. Let’s say for the sake of the argument that Nike has some, but not all of their products, made in China. You go in to buy some Nikes. And you buy the shoes thinking they were made in the US. True, you will never know. But by having a product that is made in China, American jobs are lost and child labor may have been used to make this product. Don’t you, as a consumer, have the right to know where a product was made?
Another example:
I have a neighbor who was going to hire a landscaping company. He called the company and asked, “Do you employ illegal aliens?” The foreman said, “Yes, we do” He thanked the man and politely hung up. You see he wanted to hire a company that hired US citizens. Was he wrong for asking where the employees were from?
