I don't mind a decent "hammering." It's interesting. I don't take anything personally.
As for "lacking the courage or stamina to defend my ideas", I would say that you don't appreciate the imbalance factor. Often times, all too often, it is simply my own self having to read, digest, and respond to 3+ people within a snap. All too often, I read "where'd you go?" when I'm actually responding to the guy two guys before him.
And often times... I'm pretty much done with it.
As for your "with it" comments (not new), it comes only from your sense of not being with it. I hold my political beliefs quite dearly. They have nothing to do with trend.
