I don't think you even know what you're talking about here.That is clearly a retrospective justification.
You realised there was little credible response to the freedom of expression point regarding a national flag being flown,so you upped the emotional ante by invoking the regimental flag of the Parachute regiment.
For your benefit: Tony invoked freedom of expression. I then employed a hypothetical to show how the freedom of expression argument was flawed; why not use same argument to defend the flying of a parachute regiment flag for example? Seeing this, Tony then(i.e. after, so no restrospection) elaborated by drawing a distinction between national flags and other flags.
Let me know if you require drawings :roll:
