The entire point of moderation is to keep horrible people from saying horrible things. Say things that communities find acceptable, or get on out of those communities.

I’m sure there are some other communities that will welcome your opinions, but you should really already know how unpopular that particular opinion is among the general population of the English-speaking world.

I know some gestures definitely aren’t. Nodding “yes” and shaking your head for “no” are not universal, nor is the “come here” motion or motions for eating or drinking.

One thing that IS universal is throwing your hands up in celebration of a victory. The thing boxers do at the end of a match. Even blind people who have never seen that gesture do it instinctively.
