Regret in donating sperm, but for a different reason

Here's a guy who regrets donating sperm and believes men should stop doing so.

I can't help but feel that his arguments add weight to the whole "right to know" debate, but he takes it to the other extreme that children born that way are still his.

I guess what it all comes down to is that we're both looking out for the interests of the donors, who seem to get overlooked in all the media hype focusing only on the children and the mothers.
