So, he basically goes around and punish the bad guys. I do not really see what's so Amarrian liberal in this. I would expect most conservatives and orthodox to do the exact same thing on their demesne if they truly are serious leaders.
I would however be interested to read the bit of PFs where TM supports TCMCs, even though I do not see how it necessarily makes of them fanatics like the Khanid. I can believe well enough that TM are probably damn pragmatics, but I have a very hard time picturing them like mini Khanids, especially considering their ancestry and views on "races"...
I'd link it to you, but the new website organization has made it very hard to find old news posts (old links are broken, there is no search function, and none of the race-specific channels are available at all).
Simply, in the various news reports about the TCMC controversy, we got a few bits of information:
1) They are banned in pretty much every Holding in Ardishapur.
2) Khanid Kingdom believes in the individual authority of the Holder and has instituted no official policy. However, the Slavery article outright states that they widely employ TCMCs, and it is not considered controversial there.
3) Tash-Murkon has a high amount of TCMC-supporting Holders, though there are detractors there. One of said detractors moved away from TM due to his views.
4) The Theology Council is split pretty evenly between supporters and detractors, and no official policy was instated. TC says that it is up to individual Heirs and Holders to determine if they are banned or permitted in their Holdings.
