TCs want 50% in some very vital areas, like the constitution of the country, which I believe is a very just demand and less in the others.
When you say "TCs" which TCs you mean? You and Brother? Because your leadership and probably the majority of TCs want an unlimited 50% power. If it was in just vital areas like the constitution then it wouldn't be a problem at all.
we need a system that will guarantee a lasting peace and be acceptable by both sides.
I agree. But there are many types of "acceptable". E.g. if I put a gun on your head and ask you to give me all your money, would you say you do not accept? Forcing something against democracy and human rights can not be acceptable and will not bring peace.
A federation is the only mutually acceptable solution, since both sides have already accepted it as a viable solution. It is also supported by the whole world. There are many federal democracies in the world.
Sure, but when we said we accepted federation we meant federation like the many other federal democracies you talk about. We didn't say we would agree something that will be called "federation" and that will in fact be a disguised partition that would create the best banana republic in Cyprus. E.g. Do you know any federation in the whole world that residency in a state depends on what race you are? This a human right violation and it is not a part of any federation.
We cannot just start living together
I didn't say everything should happen in one day. It can be done with transitional periods. If it took 50 years to take communities apart, then lets take another 50 to bring them together.
We can discuss the amount of power etc we T.Cs should get but asking us to subordinate ourselves to you guys is out of question
Taking your 18% properties, and your 18% power share will mean that you subordinate yourselves?
