Interestingly enough, I can empathize with that. I converted to the Catholic Church about five years ago, and was initially drawn by this and other related matters. Of course, it did not take me long to discover that the Church as it is now and the Church as it was back in the day are two very different things due to Vatican II (I'm not a traditionalist per se, although I have strong pro-traditionalist leanings).
Personally, I'd like to see monarchists organized a little better than they seem to be. I believe a good case can be made for monarchy, when it is understood properly.
Yes, this is a problem. A Portugese monarchist wrote me that royalists there (and, by extension, other countries) are in a "Catch-22" situation, because any monarchist movement, in order not to alienate any potential supporters, would have to be a single-issue movement, but people are reluctant to vote for single-issue parties because even if they support monarchy there are other issues that matter.
I also wish there were more of an English-language monarchist presence on the internet. My own site is one small attempt.
Are you familiar with the Monarchist League?
