Obviously you do not know him otherwise you would not speak like this.
Once again, the knowledge of who Andy T or anyone else knows, is not yours to possess.
Regarding the blog and actual issue, a 'royalist journalist', as you brand him, is important when it comes to delivering appropriate and important feedback and criticism towards a Royal Family as a whole, or its members.
On the issues, I find that the blog misses slightly when comparing members of the Royal Family and their fate to the character of Nora in Ibsens well-written play 'A Doll's House'. One can always analyze her choices and draw comparisons to events in the Royal House, but in the end, the metaphores would probably be lost on many of those who might read it.
I quite agree with Andy. In the end, the point of the text is seemingly lost in its long-winded way of writing and overuse of easy metaphores and fairly cheap literary tricks, and it does not serve either the monarchist agenda, or aid the republican forces much at all.
In the end, I would say that in order to qualify as a journalist to be taken seriously, one should keep ones own opinions slightly more under the radar, and write more interesting texts that do not lean so one-sided towards either side or a contentious issue. In order to qualify as a 'royalist' anything, one should be able to discuss royalist issues from multiple sides, preferably with more neutrality and generosity to the inherent complexity of the topics at hand, than this person was able to do in his published text.
