>because others see it being accidentally used

This isn't my observation. The OK sign was used explicitly to represent white supremacy by people who wanted to "troll" others into believing it was being used that way "earnestly". But using X symbol to represent Y is not something that is subject to earnestness nor irony - i.e. meaning follows usage, not the other way around (and that is not even considering the fact that a subset of people participating in the trolling did explicitly support white supremacy). That property is intrinsic to language. When you use a symbol to represent something, then it is being used to represent that thing. It is self-fulfilling. If I merely told you that some symbol X represented Y, then I would be lying. If I used symbol X to represent Y, and got a large enough group of other people to do it, then I am creating a new contextual meaning for symbol X. People reacting to its use are not "tricked". They are responding to a reality I have created.

If you cede ground to trolls, you're just going to encourage them.

Thanks for the correction! I was unaware it was troll-ish behavior from the get go.
