I was just going to say that I'm actually still not sure how one would use the flag in a way that would lead to a problem relating to section 7, but there is a restriction here. It states that the flag must be displayed in its role as a national symbol. That's paragraph 2(a).
Paragraph 2(b) states that “the display is not for an improper purpose...”. That means any attempt to use it maliciously. I could display the flag by draping it over my neighbour's car so he can't leave the driveway and that would not be permitted, or across the end of the laneway so he can't drive out without.... Also, “the flag is not subjected to desecration”. If I want to start burning flags and create a fire hazard, that wouldn't be allowed either. I think there is a reasonable limit put on it.
