Has he/she/it bothered to stay around to defend their posts on any of those threads?
What’s there to defend?
The post is about whether young voters support gay marriage. It’s overwhelmingly obvious that they do.
And it’s well established that old people are going to die soon, and young voters are more likely to vote as they get older (and unlike views on taxes, etc, it’s unlikely their views on gay marriage will change much).
I don’t see any plausible method to persuade young voters to change their minds (and certainly the rhetoric seen on a typical FR thread won’t do it - at the first “perversion” or “fornication” mention they’ll tune out or start laughing at you.)
