One person losing his job, compared to millions of people not being able to marry the person they love? Even if you figure that $1000 as a fraction of the money raised by the campaign, you're still talking about significant emotional harm to hundreds or thousands of people directly affected within CA.

But the effects are actually much greater, because the CA decision was not made in a vacuum: it affected public sentiment all over the country, and the world. Delays in full marriage equality in CA mean delays in general societal acceptance of gay people, which means more bullying of LGBT children and teenagers, more suicides, more people getting disowned by their families.

Equating the harm done to him to even a fraction of the direct and follow-on effects of the prop 8 campaign seems almost offensive, to me.

[Edit: Even so, I think the reaction was a little over the top and this outcome was unfortunate. However, I don't feel bad for him.]
