People that can't scumhunt say "scummy" when they know they're guessing, or as just as an excuse to fos someone. It's mainly a tool to suppress rational thought.
Instead of just spamming "scummy" define what you mean. Don't accept people using "scummy" as reason, make them define what they meant. If you've bandwagoned a lynch because someone said "scummy", you're a sheep and you need to stop letting people guess for you. This applies to self voting, but that a separate topic.
Don't be scared to be wrong, if you don't act on your convictions, how will ever affirm them?
"objectively scummier" here is meant as "exhibiting specific scumtells that pattern-match to things that ought to be lunched," such as loudly fencesitting, appealing to unclears, or having fake/unrealistic reeds. i think there is no porblem with the usage of the term here.
in fact, i would say 'your gut' better captures the message u were tryna portray, OP. i mostly agree with that message except that its less about the vernacular and more about dumnobs being dumnobs.
