Simply assuming that a group of people with delusional parasitosis who made up a disease name and started a support group (those are the facts) actually have a disease doesn't help them in any effective way. In fact by coddling their delusion their underlying problem goes untreated. Why any rational person would want this to happen is beyond me.
The “manipulation of nature” as you put it has been going on since humans first cultivated crops and raised livestock. Simply assuming that “big farming” is involved in some conspiracy and or cover up of a disease that we know was made up by a group of people with delusional parasitosis makes you sound a bit delusional. Especially when you can't even remember the name of the disease in question.
There are none so blind as those who will not see.
