Just makes it look like people jump on the virtue signalling bandwagon when they espouse opinions that aren't broadly consistent with their actions. Like eating beef several times a week, but feeling compelled to bring up the killing of pilot whales in amounts that are not at all concerning from a species conservation point of view.
I don't think many people live entirely ethically consistent lives. I sure don't.
That doesn't necessarily make every ethical boundary they try to have "virtue signaling".
