"These people who throw milkshakes could be throwing acid"

No, they couldn't. They made a conscious decision to throw a milkshake at someone because a milkshake is not going to hurt that person. It won't burn them. It won't injure them. It won't damage them in any way other than to get milkshake on them.

Throwing milkshakes and throwing acid are two WILDLY different things and to try to suggest they are the same is just bullshit.

It's like throwing a chair in a pool and throwing a baby in a pool.

Re: politics

Im thinking maybe something like "calling protesters terrorists for kicking over a trashcan"

Politics specifically, nothing. But if you are the kind of person who violates the social order, no matter how mundane or harmless your behavior is when you do it, don't be surprised when people don't want to have you around anymore. They don't want to see the kind of behavior you demonstrate when you realize that consequences don't apply to you for whatever reason.

If you want a political example, a pardoned January 6th insurrectionist is currently in the news for threatening the house minority leader.

People don't remember the "9 times out of ten" you were cool as hell, they remember the one time you crashed out and made everyone feel uncomfortable or unsafe, and they think about that every time someone has to decide whether to invite you out somewhere.
