Earlier quoted context omitted.
The only person here I see here who's virtue-signaling is Trump, by making statements that are widely acknowledged to be just for show and not serious promises.
Another one-way function? Only people I declare "other" and bad can be guilty of virtue-signaling. Hard to keep up.

My definition of "virtue signaling" is the practice of loudly proclaiming that you believe X because of the benefit to your reputation from people seeing you proclaim X and not because you particularly care about believing X (and maybe you don't), a "they love to stand and pray in the street corners" thing.
I find it hard to believe that people in this pledge are using it to enhance their social status; there are a lot of people in the pledge, and coverage tends to focus on aggregate behavior (e.g., how many people from Facebook have signed), not individuals. Only one signer is quoted in this article, at the very bottom. And I think the people signing are genuine in their beliefs.
Meanwhile, quoting the comment above: "Trumps pre-election stuff was BS, nothing will be done." It's BS that people wanted to hear, and it got him elected to the most powerful office in the world. It is, quite literally, stuff he proclaimed because it enhanced his social status that he didn't actually care about intrinsically.
I'm not sure what this has to do with people being other or bad (unless you think that virtue signaling makes someone other and bad, but I didn't say anything like that).
