Nothing you posted debunks it. You are acknowledging that the duly elected leader was removed from his position without following the constitutional process. The rest is just noise, including that unanimous vote - yea of course people are going to vote that way when there are violent armed insurrectionists around.
No, there was nothing unconstitutional about the process. The Ukrainian parliament correctly followed the procedure for holding snap elections.
Snap elections might be a novel idea for Americans who are used to presidents always serving the full term, but they are fairly common in rest of the world. Germany held snap elections just last Sunday, after the government lost its majority in parliament.
So you are saying that a unanimous vote is more likely a coup than a reaction to the horror of the president ordering an attack on innocent protesters? An attack that killed some hundred people, in fact.
I guess you could call that a "coup." I guess I could argue that war is peace, too. Both could be called propaganda.
