Consumers are voters, so it's both. The number of voters one can productively engage about thoughtful GMO regulation is basically zero. People are against it or don't care.

It is a problem with GMO labeling requirement. GMO labeling requirement should be abolished because it is a meaningless distinction and consumers have no right to know such things.

I can understand why someone would argue it's a meaningless distinction. I don't agree with the idea that a consumer has no right to be informed. Let the consumer know, make the case that your product (any product) is safe, and let the consumer decide.

My stance on GMO labeling is analogous to kosher and halal foods. Consumers can and do demand arbitrarily meaningless standard such as kosher, halal, or GMO-free. I am even in favor of protecting such labels by advertising standard law: i.e. forbidding things to be labeled kosher if it actually is not kosher. But GMO labeling requirement is as ridiculous as kosher labeling requirement.
