I never said that you should shut up about one and not the other. How did you come to that conclusion? I am saying that they should be viewed from different perspectives: one as a moral issue, the other as a domestic political issue.
Well you think that Trent should behave differently and not say what he thinks because that is unpatriotic in the case of the referendum but not in the cases of the war. That seems to be saying what I suggested.
Again simply saying that one thing is a moral decision and another a political one (not sure what the addition of 'domestic' is intended to do there), is not making a case for them being treated differently in the way you are suggesting. Indeed it appears that you are in a form of circular argument where you say they should be treated differently and when asked why say because they are different.
All that is leaving aside that you have not made the case that they can actually be described as moral issues or political issues. Indeed the idea that you think Trent should behave in a certain way here seems to make it sound as if you see this as a moral issue.
