I think it is important to point out the failings of others. Otherwise they may not connect the dots and learn from their mistakes.

Sometimes a mistake is innocent, say you forgot to zip up your fly. It’s important to know you forgot to do so as it could be very socially embarrassing.

Sometimes one could accidentally cut someone off in traffic because they didn’t see them. A good honk notifies them of their mistake and will hopefully drive home the fact that they probably need to pay better attention to traffic.

Pointing out that abstaining and or choosing not to vote enabled the election of the greater of two evils is equally important.

Rock on OP. Never let them forget!
