As with many others, I agree most kilts with a "flag" design, are firstly designed as a kilt, and the flag represented is intended to be honored in it's use.

Therefore I don't have a problem with them in general. There is also the fact that others may find offense with them, and dealing with that can cause difficulties while wearing them.

This is, and always will be a sensitive subject, for some more than others, so as MacWage states:
Now gents and lasses, lets try to keep this civil and out of lockdown.
