Giardia/Entomoeba Histolytica and other protozoa are hell. We suffered too much and we don't want to see others suffer the same. Its hard to put in to words the amount of misery and pain those bugs put me through. My self and others have tried many natural and allopathic medicine without success and because of this experience I understand how one is quick to react to suggestions of non specific alternative treatments that does not seem to be proven against protozoa. However, I agree that if we tone down a bit we might be better received by others. (so, I basically agree with what you said)
I tend to be open to alternative treatments, but it has to be well tested and proven. I also believe in using the right tool for the job. So far only allopathic medicine has worked against my giardia and amoeba situation, but even allopathic have failed me (& failed others) due to doctor incompetence and the bugs being really hard to kill.
ps. there has been a number of comments which are not productive to the forum. You might want to take a look at the recent threads for future reference when someone send you an alert. You can start by looking at the last messages of the previous couple of threads and you will see what I'm talking about.
