if things get bad enough I will run up the Confederate Battle Flag instead .... I’ve got a nice 5x8

If it is 5X8, it is a Confederate Naval Jack. The battle flag is square - 1X1 aspect ratio. IIRC

But very few people know the difference and they will get the message.

you are correct , but in one regard :
Rectangular CBF’s were flown in the western theater quite often . NBF had his own version , Joe Johnson also authorized it’s use .
In the ANV the perfectly square forms were the CBF
