No offense, but you know nothing of my tithing to this situation. I don't feel a need to defend myself to you. But, I'll tell you that I do volunteer at a few places, and it is none of your business. And you have no idea how many people I sponsor on a weekly basis whether it's in person or on the internet. I'll not list them or my projects because to do so undermines why I do it.
Just because someone has a strong position on vaccines and their KNOWN poisons does not mean that they don't lend a hand to help the situation in other ways. Helping answer questions for people on these many forums is one element of helping. Just because some of it is done electronically does not negate its sincerity or validity.
