Depends on how you define conservative - Invelious's distaste for foreigners is a fairly extreme (and impressive) example. Much of the liberal/conservative distinction these days seems to revolve around the slavery debate (I think) - so what would a liberal or conservative look like aside from that issue? Is there any form of house loyalty or infighting within the Amarr community? What political issues are there outside of slavery? The legitimacy of the Empress? Or have people stopped caring about that?
Actually slavery is just a fairly minor part of the deepest divide between nowadays ultra liberals and the traditional conservatives (the amarr bloc).
The true divide is the question of the supremacy that is inherent in the true believers, and especially the right of the True Amarr to rule and lead.
Your comments about Jamyl pretty much show off how sadly limited most peoples views are nowadays. It seems to me that it all boils down to "omg slavery" and "omg Jamyl is cloned" for most people.
However, the scriptures outright state that the true amarr, the first believers, are destined to rule over everyone else, to lead the non-believers to God etc. This view has been backed since ever at least I can remember - and I only joined very recently in the big picture.
The distaste for foreigners / xenophobia comes, in my experience, mostly from the simple fact that most True Amarr, and in kind the Khanid and Ni-Kunni, have a huge superiority complex centered around their heritage. As many chronicles and news articles have pointed out the amarr usualy view events in a more long term way than, say, for example the federation or the republic. The simple fact that the leaders of the empire live for multiple centuries pretty much cements that impression, such a long lifespan will certainly behoove you to plan ahead.
Now, back on topic.
The contemporary ultra liberals are very happy to mingle with non-amarrians and take on their customs, be that just for show or for real.
While this strikes me personally as quite uncharacteristic of the amarrians described in the PF I'll deal with what I see, and if people want to be their own special snow flakes they can be my guest, I'll be happy to include them in my RP.
It is a (sad?) fact that the old school liberal/conservative line has been dragged way to the left end of the spectrum.
PIE used to be considered dangerously liberal by many, and while we may have slightly edged more to the right wing we are still pretty Heideranian. Now, Kotmc for example, is very happy to openly flaunt their ultra liberal convictions, their members frequently speak their very mind in public, sometimes even without, or against, the will of their superiors. This goes very much against the trend that has been established, by both CCP and the amarr bloc, ever since the servers went life - and in some cases even before that.
Many people have stopped to care about the intra-amarrian politics when FW came along, something we had predicted beforehand.
There still are a lot of issues on the table, but, at least in the conservative circles, such internal debates are obviously kept private and behind closed doors. This is, by the way, again typical for the 08/15 PF amarrian, who will happily stick a knife in his bosses back, but wouldn't dare talk down to him anywhere.
