That is the argument.

> Finally, we have to contend with the fact that people earnestly believe in the things they say and do. If it were just for optics and they didn't actually hold their positions, these issues would be far easier to deal with.

The point of the argument isn't that people don't genuinely believe these issues. Its that they participate in these views in earnest because of social conformity as opposed to a genuine understanding of, and commonly without any intention of helping resolve them. The symptom then is blindly electing leaders with no real plan (or worse) and the result is predictably poor outcomes. Its used as a battering ram in discussions; I thought it was a dog whistle too before moving out to the West coast by my god it really is everywhere here, and it really does stifle discussion. Its a real issue.

No, then it would have been easier. Virtue signaling is so hard to deal with since people don't want to lose their virtue, they have to stay the course and continue to upheld that what they did was virtuous or they lose all their hard work.

A good sign is if you call your opponents names rather than try to win them over, then you are just virtue signaling instead of trying to fix anything, insults doesn't improve anything except act as signaling. This is how most politicians acts, it tend to make you very popular and make your tribe view you as very virtuous, virtue signaling works.
