Folks displaying Tr×mp signs and hate symbols in the US are begging for others to come onto their property & vandalize their shit, just so they can do violence against the offenders.
If you plan to vandalize something, please be cautious. I've seen FB posts about how they'd love for "liberals to try and take it down so I have an excuse to open fire."
I thought about it, even though my archery skills are near nil
That said, the only way it'd work is if the arrow had a mechanism to grab the flag.
The other way I would do it is if it was a trespass with people with military training who can watch my back while I lower the flag and replace it with the proper Confederate flag.
What it some Nazi dickbag runs a Nazi flag up someone else's pole? They don't deserve their shit burned down, but I can see no case in which the flag itself isn't fair game.
