From the About section:
GMOAnswers is an acknowledgement that we need to change. The site was created to do a better job answering your questions – no matter what they are – about GMOs. The biotech industry stands 100 percent behind the health and safety of the GM crops on the market today, but we acknowledge that we haven¹t done the best job communicating about them – what they are, how they are made, what the safety data says.
This website is the beginning of a new conversation among everyone who cares about how our food is grown.
With regard to labeling, please review the following responses which address this topic: http://gmoanswers.com/ask/you-have-answered-very-thoroughly-your-reasons-opposing-labeling-gmo-products-you-also and http://gmoanswers.com/ask/regardless-whether-or-not-you-believe-gmos-are-good-or-bad-what-harm-labeling-them-so-consumers.
One passage addressing your question states:
“As believers in GM technology, and having seen the benefits nurture farmers and society alike (Check out GMOs and the Future of Agriculture). The harm comes from a label that conveys to consumers that food made from farmers’ crops grown with our seeds is somehow less safe or nutritious or somehow different from conventional or organic food. This is simply not the case. We believe a government requirement to label a food “GMO” would do just this, and a recent study conducted by an MIT professor supports this view [See Policy and Inference: The Case of Product Labeling].”
