formerbabe, er, no, I don't "routinely wish harm to those who think differently" to me.
That's kinda the point. Recent politics has been particularly focussed on divisiveness, and the attempt to push people into opposite "teams", which are encouraged to treat each other as The Enemy. So, for many people it's important to make clear that we have more in common and that we're supportive of each other on a human level, despite having major differences. And that we don't save our good wishes for those "on our team."
Another reason is that some people confuse support for someone as a human being, for support for their personal behaviour or political actions. The media can be a bit prone to this, and it's a mistake.
