I am an environmentalist. It's how I make my living. I work exclusively on Green initiatives. I help green companies and products make themselves available to the public. I help them get their products into the marketplace. And I help further the discussion of future products. These are people who are making much less money than they could be making but they would rather save the human race.
I work with the kinds of environmentalists who have things like....I don't know....PhDs from MIT. Good people. Smart people. Reasonable rational people who want to do good for humanity.
You didn't just say those things about me. You said them about a whole host of people I respect and care about.
Some environmentalists my be crazy and they may do horrible things. That doesn't mean it is true of every environmentalist. It doesn't excuse what you wrote.
Stalin was an atheist. By your logic, that makes you a mass murderer and a tyrant.
I don't care if you realized the claims you made applied to me. You were wrong to make them regardless.
