I'm not gonna yell, but I think I would explain it differently and clarify different points.
--Persian Jews aren't Sephardim, their community in Persia pre-dated the community of Jews in Medieval Spain. But it's true that they were not part of the Ashkenazi modernization thing, with the various movements (Hasidism/Mitnagdim, the Haskalah and its offshoots, the Reform movement and its offshoots, etc.) I'm just saying this because you asked about a Persian Jew, not because where people are from predicts anything.
--The movement or denomination known as Reform has participants called Reform Jews. They are not Reformed Jews. They are still in the same shape they were before.
--The Conservative movement gets a capital C because otherwise these Jews who are politically liberal who belong to a Conservative synagogue will be all weirded out.
--I think the Reform movement has a theology of a "messianic age" and I'm not sure about the Conservative movement.
I don't think it's accurate to say that the reason that Ashkenazi Jews have denominations is that we wanted to be like our neighbors and Sephardim (and other Jews living in Muslim countries) didn't. If you look at the countries where Reform developed in the early 19th century, you will see that all had a substantial Protestant presence or were majority Protestant. (Germany, the US and Britain--yeah there were Reformers in Hungary but it didn't really take off there.) The Reform movements got strong in countries where Christians had the idea that they could shape their religion to fit their ideology rather than the other way around. That's the reason why Reform has the most followers in the US and why the Conservative and Reconstructionist movements were started here. It's also why the "movements" are so weak in Israel.
If you look at the actual observance of US Jews who i.d. with different movements, you might find that some folks who affiliate with a Reform Temple have the same observance as Jews who affiliate with an Orthodox schul. There are both aesthetic and ideological reasons to affiliate with a movement, beyond being too lazy to keep kosher, you know? For one thing, some people might be Shabbat observant but think it's immoral not to count women in a minyan. (Or the other way, drive to synagogue on Saturday but feel just too weird about women being rabbis.)
It's also true that today, US Jews with origins from every country are being drawn into the denominational thingie because they move to places where they have to chose between different congregations.
Back to the messiah question: I think that just because someone is affiliated with this or that synagogue, you can't predict from that what they believe. The official line of the synagogue is one thing, what the individual believes is another. The number of influences that any individual Jew could experience is staggering...
I know, I'm no help.
