PSA and reminder:
The terms "blacklist" and "whitelist" are racially charged. Please use "blocklist" and "allowlist" instead.
Yes, the terms are old. Yes they're not directly based on race. But they _are_ based in the systemic idea that "white == good; black == bad". Just because something is traditional doesn't mean it's acceptable.
It took me a while to see just how insidious little things like this are, too. It's ok to take some time to understand. Just please switch terms while you do.
Hit the nail on the head there lad. Virtue signalling... it's the new fidget spinner.
Unfortunately it has a longer life expectancy than, say, Pokémon Go, but it's a fashion statement with about as much depth.
Virtue signalling and Pokémon Go both feed on reward-motivated behaviors, i.e. the anticipation of reward increases the level of dopamine in the brain, but virtue signalling rewards are slightly more sophisticated than collecting gifs.
