Yes indeed Richard.
Here in Scotland raising the Union Jack can often be misinterpreted as support for a certain soccer club which seems to have "adopted" the Union Jack as their own.
I would NEVER raise a Union Jack here in Scotland nor would I have the Union Jack pattern on any of my personal effects, keyrings etc, not even on my internet home page, yet when I go just a few miles over the border to do a day's volunteering at the air museum I am proud to raise their Union Jack on their flagpole.
Though it is not unheard of for supporters of said football club to occasionally be seen wearing kilts!
