Yes, very well said.
So, you're saying that you hope people over fifty die because you believe they deny your status as an equal person? When I was called a fag by a black kid a few weeks ago in Harlem, how should I have treated him? Should I hate all black kids because it's safe to assume most blacks aren't in favor of gay equality? Where does that madness stop? If one were to adopt your "culling" method, we'd be reduced to a quivering, shaking, fearful, resentful, bitter and fragmented society of paranoids. That doesn't sound like a happy, healthy society, does it?
And again you state that people's feeling on his forum are hurt, and I insist that is not the case. I suspect people wonder about your thinking, but aren't harmed or hurt by it. Most people struggle to wrap their arms around your view.
I enjoy the challenge of changing minds -- I truly do. I don't always, or even often, win outright. Sometimes a seed is planted and sometimes that seeds takes root -- sometimes it doesn't.
As Obama himself said, "if you can change a vote, you can change a city; if you change a city, you can change a state; if you can change a state, you can change a nation; if you can change a nation, you can change the world." But you can't change much by sitting around, wishing people older than fifty would just do their duty and die. That's not a viable political philosophy, that a mentality of resentment and passivity.
