I don't think so. In order to be virtuous, one should have some skin in the game. I would respect dedicated pacifists in Kyiv a lot more. I wouldn't agree with them, but at least they would be ready to face pretty stark consequences of their philosophical belief.
Living in the Silicon Valley and proclaiming yourself virtuous pacifist comes at negligible personal cost.
People don't participate in murder and they think others shouldn't either.
People don't participate in wars (which are essentially large scale murder) and they think others shouldn't.
Murder happens anyway. War happens anyway.
Yet if someone says 'war bad' people jump and say 'virtue signaling', but no one does that when people say 'murder bad'.
There's some really weird moral entanglement happening in the minds of people that are so eager to call out virtue signaling.
