The problem with changing whitelist to "allowlist" is that it implies that people who use whitelist are racists. You're not just virtue signaling (and confusing my spellchecker) but causing discord.
It would be perfectly fine if people switched to "allowlist" because they think it's a better term, but that's not the reason. They do it because they want to virtue signal or they're afraid of their peers (because they'll be called racists).
Using "allowlist" is actually bad because it gives agitators power and they keep changing more words to get more power.
I personally don’t assume people who use whitelist are racist, or those who allowlist are virtue signaling.
However, I certainly do assume that people who chastise others for using “whitelist” are virtue signaling, and those who deride people for using “allowlist” are racist.
Both are easily understood and I generally assume good intention from people. Just live and let live.
